How we can work with output cache programmatically ?

Once I got an interesting question from one of our discussion lists about how we can enable output cache programmatically ? and how we can create a cache policy through code. After my research on it I was able to accomplish this one by using the following code snippet.

    1: using Microsoft.SharePoint;

    2: using Microsoft.SharePoint.Publishing;

    3:  

    4: SPSite oSite = new SPSite("https://blr3r7-19c:6000/sites/CacheTestSite");

    5:  

    6: SiteCacheSettingsWriter oWriter = new SiteCacheSettingsWriter(oSite);

    7:  

    8: oWriter.EnableCache = true;

    9: oWriter.EnableDebuggingOutput = true;

   10: oWriter.AllowPublishingWebPageOverrides = true;

   11: oWriter.AllowLayoutPageOverrides = true;

   12: // second parameter is the id of the cache profiles in the dropdown. Once you create you custom profile that profile also will come under this dropdown

   13: oWriter.SetAnonymousPageCacheProfileId(oSite, 2);

   14: oWriter.SetAuthenticatedPageCacheProfileId(oSite, 2);

   15:  

   16: oWriter.SetFarmCacheFlushFlag();

   17: oWriter.Update();

Creating custom cache profile:

Cache profile is nothing but a list in a publishing site. Thus you have to create a new custom profile list item with all the metadata.

    1: SPList oList = oWeb.Lists["Cache Profiles"];

    2: SPListItem oListItem = oList.Items.Add();

    3: oListItem["Title"] = "custom profile";

    4: oListItem.Update();

If you want to get the current cache setting of a site through code you can use the following line of code.

SiteCacheSettings oCacheSettings = SiteCacheSettings.GetSiteCacheSettings(oSite);

You can see the site collection cache profiles under the Site Collection Administration of a publishing site.

  Is there anyway possible that we can get the status of "Site Collection Output Cache Settings" http://SiteCollectionURL/_Layouts/sitecachesettings.aspx using SharePoint Object Model. Tried "SiteCacheSettings" but not able to get the status. Any help?
