824684 Description of the standard terminology that is used to describe Microsoft software updates

The System.Net.HttpWebRequest class in the .NET Framework 2.0 may parse the Request-URI to remove or to replace certain characters to follow the HTTP Request for Comments (RFC) guideline. During the parsing, the System.Net.HttpWebRequest class replaces &quot;//&quot; in the Request-URI with &quot;/&quot;. However, this change does not comply with HTTP 1.1 RFC.

For more information about the HTTP 1.1 RFC URI, visit the following World Wide Web Consortium Web sites:
