The Web content management capabilities in Microsoft Office SharePoint Server 2007 can help you communicate more effectively with employees, partners, and customers. By providing easy-to-use functionality to create, approve, and publish Web content, Office SharePoint Server 2007 enables you to get information out quickly to intranet, extranet, and Internet sites, with a consistent look.

You can use Web content management capabilities to create, publish, manage, and control a large, dynamic collection of content. Web content management, as part of Enterprise Content Management (ECM) in Office SharePoint Server 2007, can help streamline the process for creating and publishing Web sites.

You can also use the Web content management features in Office SharePoint Server 2007 to:

Manage variations of content for different devices.
Publish content to intranet, extranet, and Internet sites.
Author Web content in a WYSIWYG (what you see is what you get) environment.
Manage site content, structure, and deployment.
Use document converters to convert Microsoft Office InfoPath 2007, Microsoft Office Word 2007, and XML files.
Establish an approval process to ensure that content is reviewed before it is published.

Manage cache setting

You can manage the following cache settings in Web content management:

Settings for Page Output Cache Policy property for site collection
Settings for Page Output Cache Policy property at site level
Settings for Site Collection Object Cache
Settings for creating cache profiles

Manage disk-based cache settings for a Web application

Disk-based caching is one way in which you can achieve faster processing of content stored in a Web application database. If your Web application contains large files such as images and multimedia files, enabling disk-based caching improves page delivery time, because the cache stores files on the front-end Web server, thus reducing database traffic.

You can enable disk-based caching in the Web.config file in the Web application to which you want to apply it. For this you need to configure settings in the BlobCache section of Web.config.

Note

Disk-based caching is referred to as BLOB (binary large object) caching within the Web.config file.

The following table lists the default settings for disk-based cache settings for a Web application.

Parameter name	Parameter description	Default setting
Location	Directory specified for the cache element.	%Installdrive%\blobCache
Path	To add new file types to the BLOB cache.	\.(gif\|jpg\|png\|css\|js)
maxSize	To change the size of the cache.	10 gigabytes (GB)
enabled	For enabling the disk-based cache.	false

Manage page output cache settings for site collection

The front-end Web server uses the page output cache to store rendered output of all controls for a given page, and then store different variations of this pre-rendered page. After a page is rendered for a user in a given user class, each time the user views that page again, the page loads faster, because the controls on the ASPX page do not need to run again to generate the HTML. Thus, the time required to render the page is reduced. The page output cache can improve server performance, because it reduces server control activities and calls to the database.

The following table lists the default settings for the Page Output Cache Policy property for a site collection.

Property name	Property description	Field	Field description	Default setting
Output Cache	Output cache stores rendered output of all controls on a given page, and then stores several different variations of this pre-rendered page.	Enable output cache	Select to enable the output cache.	Clear
Default Page Output Cache Profile	A cache profile specifies how long items can be held in the cache. It also describes how the caching system determines whether a cached page element is valid for other requests for the same element from different users.	Anonymous Cache Profile	Select this option to provide this property to anonymous users. You can select the Disabled, Extranet, Public Internet, or Intranet cache profile.	Disabled profile
Authenticated Cache Profile	Select this option to provide this property to authenticated users. You can select the Disabled, Extranet, or Intranet cache profile.	Disabled profile
Page Output Cache Policy	Allows administrators and page layout designers to choose a different page output cache profile from the profile specified in the default Page Output Cache Profile.	Publishing sites can use a different page output cache profile	Select this option to use a different page output cache profile for Publishing sites.	Clear
Page layouts can use a different page output cache profile	Select this option to use a different page output cache profile for Page layouts.	Clear
Debug Cache Information	Displays additional cache information about pages in the site collection. This includes the date and time that the page contents were last rendered.	Enable debug cache information on pages	Select to enable debug cache information on pages.	Clear

Manage page output cache settings at site level

The following table lists the default settings for Publishing Sites Output Cache Settings for the Page Output Cache Policy property at the site level.

Property name	Property description	Field	Field description	Default setting
Page Output Cache Policy	Specify a cache profile for caching page output for anonymous users, and a cache profile for caching page output for authenticated users.	Anonymous Cache Profile	Select the inherit option to inherit the settings applied at the site collection level, or select a pageoutput cache profile option.	Inherit is selected by default
Authenticated Cache Profile	Select the inherit option to inherit the settings applied at the site collection level, or select a page output cache profile option.	Inherit is selected by default
Apply these settings to all subsites	Select this option to apply the cache profile settings to all the subsites.	Clear

Manage the object cache

The object cache is used internally to optimize page rendering by storing properties of sites, page layouts, and pages. The object cache reduces the amount of traffic between the Web server and a SQL Server database. This results in higher throughput of rendered pages, thereby increasing the number of pages that can be delivered to clients.

The following table lists the default setting for Site Collection Object Cache Settings.

Property name	Property description	Field	Field description	Default setting
Object cache size	The object cache is used internally to optimize page rendering by storing properties of sites, page layouts, and pages.	Max. Cache Size (MB)	Set the maximum size for the object cache, in megabytes (MB).	100 MB
Object Cache Reset	Specify settings for flushing the entries in the object cache.	Object Cache Flush	Set this option to flush all entries in the object cache.	Clear
Force all servers in the farm to flush their object cache	Set this option to flush the object cache of all the servers in the farm.	Clear
Disk Based Cache Reset	Specify settings for flushing entries in the disk cache.	Force this server to reset its disk-based cache	Set this option to flush all entries in the disk cache. Otherwise, the expiration of items is managed with items being removed as they are changed in the site or when the disk size is exceeded.	Clear
Cross List Query Cache Changes	Checking the server each time a cross-list query runs produces the most accurate results at the possible cost of slower performance across the site. Cross-list queries initiated by the Content Query Web Part, or other custom implementations, can use up server resources. Specifying the time to cache the results of a cross-list query can positively impact cross-list query performance, but may display results that do not reflect the most recent changes to the items returned by the query.	Check the server for changes every time a cross-list query runs	Select to check server for changes.	Selected
Use the cached result of a cross list query for this many seconds	Select this option when changes are not frequent on the server and you want to use the cache result of the cross-list query.	60
Cross List Query Results Multiplier	Retrieves data from the server for a cross-list query. Specify a large number to retrieve more data from the server; this is ideal for site collections that have unique security applied on many lists and sites. Specify a small number to consume less memory per cross-list query; this is ideally suited for site collections that do not have unique security on each list or site.	Cross-list query multiplier	Set the value of the multiplier.	3

Manage cache profiles

Cache profiles contain specific cache settings for each type of page output cache. A cache profile determines the following types of cache behavior:

Length of time that items should be held within the cache
Security-trimming policy
Expiration of settings, such as duration and changes
Partition of a cache based on user permission, user rights, and other custom variables

There are four default cache profiles:

Disabled
Public Internet
Extranet
Intranet

You can centrally define a cache profile for a site collection; thus, when you update a profile at one place, the change is implemented across the site collection.

The following table lists the settings for creating a new cache profile.

Property	Description	Default setting
Title	Title for the cache profile.
Display Name	Display name is used to populate the list of available cache profiles for site owners and page-layout owners.
Display Description	Display description is used to populate the list of available cache profiles for site owners and page-layout owners.
Perform ACL Check	Selecting this option ensures that all items in the cache are appropriately security-trimmed. If you do not select this option, performance is better, but you should limit the Not selected option to sites or page layouts that do not have information that needs security-trimming.	Not selected
Enabled	Selecting this option turns caching on. If you do not select this option, caching will not take place anywhere this profile is selected.	Not selected
Duration	The duration, in seconds, to keep the cached version available.
Check for Changes	When this option is selected, each page request is validated for site changes; when changes are detected, the cache is flushed. If you do not select this option, performance is better, but there will be no check for updates to the site for the number of seconds specified in Duration.	Not selected
Vary by Custom Parameter	As specified by HttpCachePolicy.SetVaryByCustom in ASP.Net 2.0.
Vary by HTTP Header	As specified by HttpCachePolicy.VaryByHeaders in ASP.Net 2.0.
Vary by Query String Parameters	As specified by HttpCachePolicy.VaryByParams in ASP.Net 2.0.
Vary by User Rights	Selecting this option ensures that users must have identical permissions on all securable objects to see the same cached page as any other user.	Not selected
Cacheability	As specified by HttpCacheability in ASP.Net 2.0. There are six types of cacheability: NoCache Private Server ServerAndNoCache Public ServerAndPrivate
Safe for Authenticated Use	Select this option for only those policies that you want to allow to be applied to authenticated scenarios by administrators and page layout designers.	Not selected
Allow writers to view cached content	Select this option only for scenarios that apply to a page that you know will be published and that do not have any content that might be checked out or in draft format.	Not selected

Manage variation settings

In Web content management there are different settings for variation.

Variations

Maintaining a number of different versions or variations of publishing sites or pages is difficult and time-consuming, because it can be difficult to coordinate the creation and updating of content between the variations. To simplify this process, site owners can define a series of site variations and mark one as the primary, or source, and another as the variation.

The following table lists the different settings for variations.

Property name	Property description	Field	Field description	Default setting
Variation Home	Specify the site address from which you want variation. Variation of the specified site includes its subsite also.	Location	Specify the address of the site that is the starting location for creating the variations of this site. Note For a site collection, precede the address with ‘/.
Automatic Creation	Automatically create variations when the site is created or a new page is published.	Automatically create site and page variations	This option is used when you want automatic creation.	Selected
Do not automatically create site and page variations	This option is used when you don’t want automatic creation.
Recreate Deleted Target Page	A new target page should be re-created when the source page is republished if the previous target page has been deleted.	Re-create a new target page when the source page is republished	This option is used to re-create a deleted target page.	Selected
Do not recreate a new target page when the source page is republished	This option is used when you don’t want to re-create a deleted target page.
Update Target Page Web Parts	Web Part changes from the source page should be updated to existing target pages. Note that personalization will be lost during the update.	Update Web Part changes to target pages when variation source page update is propagated	This is used when you want to enable the update to the target page Web Part.	Selected
Do not update Web Part changes to target pages when variation source page update is propagated	Select this option when you do not want to enable the update to the target page Web Part.
Notification	Sends an e-mail to the contact person for the welcome page of the target site when a new subsite or page is created, or the contact person for a target page when this page is updated with revisions from the source variation.	Send e-mail notification to owners when a new site or page is created or a page is updated by the variation system	Select this option when you want to send an e-mail notification.	Selected
Resources	Describes whether a new page variation uses the same resource as the original page or uses a copy of these resources created in the location of the new page.	Reference existing resources	Select this option when you want to use the resources of the original page for new page variations.	Selected
Copy resources	Select this option when you want to copy the resources of original page to the location of the new page.

Variation label

Publishing sites can be tailored for different cultures, markets, and languages. Variation settings enable site owners to create and maintain a number of different versions, or variations of publishing sites or pages. Variation labels are the names given to each of the variants. For example, variant labels could be language names — such as English, French, or German — or devices, such as personal digital assistant (PDA).

The following table lists the settings for creating a new label.

Property name	Property description	Field	Field description	Default setting
Label and Description	Specify the name and description for the new variation label.	Label Name	Name of the new variation label.
Description	Description of the new variation label.
Display Name	Set display name for the label. Most display names are localized versions or user-friendly versions of the label.	Display Name	Select this option to show the name to the user.
Locale	Select a locale value, such as Arabic, Chinese, or English.	Locale	Select locale for the variation.
Hierarchy Creation	This label's structure will be built based on the source hierarchy during Hierarchy Creation.	Publishing Sites and All Pages.	This option is used for publishing sites and all pages.	Selected
Publishing Sites Only	This option is applicable only for publishing sites.
Root Site Only	This option is applicable only for the root site.
Source Variation	Set the variation label for source variation. If you select this option, then you must select the Publishing site template you want to use.	Set this variation as the source variation		Not selected

Document conversion

Site administrators can enable document conversion so that end users can convert documents from one file format to another. Document conversion for site content types allows site administrators to configure content types to store settings that define which converters are available and how those converters work on documents of that content type. A number of document converters are included with Office SharePoint Server 2007, and your organization might have additional, custom converters as well. After document conversion is enabled in Central Administration, the converters are available by default for all site content types that can be used in a document library. This includes the following content types:

Document content types, such as Basic Page, Document, Form, and Picture
Page layout content types, such as Article page, Redirect page, and Welcome page
Publishing content types, such as Page, Page Layout, Publishing Master Page

A document converter is a custom executable file that takes a document of one file type, and generates a copy of that file in another file type. For example, a document converter might take a Microsoft Office Excel file and use it to generate a Microsoft Office PowerPoint file. Using document converters, you can transform your content into different versions to suit your business needs. Perhaps you want to convert draft documentation into a different, final format for long-term archiving; or perhaps you need to convert your internal documentation to a different format for placement on a customer-facing site.

The following table lists the converters available all site content types that can be used in a document library.

Converters	Default status
From InfoPath Form to Web Page	Selected
From Word Document to Web Page	Selected
From Word Document with Macros to Web Page	Selected
From XML to Web Page	Selected
