The RegisterPrefix method registers WebRequest descendants to service requests. WebRequest descendants are typically registered to handle a specific protocol, such HTTP or FTP, but can be registered to handle a request to a specific server or path on a server.

Duplicate prefixes are not allowed. RegisterPrefix returns false if an attempt is made to register a duplicate prefix.

NoteNote:

The HttpWebRequest class is registered to service requests for HTTP and HTTPS schemes by default. Attempts to register a different WebRequest descendant for these schemes will fail.
