Remarks

CUrl allows you to manipulate the fields of a URL, such as the path or port number. CUrl understands URLs of the following form:

(Some fields are optional.) For example, consider this URL:

https://someone:secret@www.microsoft.com:80/visualc/stuff.htm#contents

CUrl::CrackUrl parses it as follows:

Scheme: "http" or ATL_URL_SCHEME_HTTP
UserName: "someone"
Password: "secret"
HostName: "www.microsoft.com"
PortNumber: 80
UrlPath: "visualc/stuff.htm"
ExtraInfo: "#contents"

To manipulate the UrlPath field (for instance), you would use GetUrlPath, GetUrlPathLength, and SetUrlPath. You would use CreateUrl to create the complete URL string.
