If a content provider is publishing to your server with the WebPost API, you must convey the name of the server to which content will be posted. If you do not specify your PostInfo file, you must also tell them the PostingURL and TargetURL. WebPost API performs a GET against the virtual root of the TargetURL server to determine the location of the PostInfo file on the server. The WebPost API then retrieves the PostInfo file and parses out the PostingURL and TargetURL if they were specified earlier. If either the PostingURL or the TargetURL were not specified, the content provider must enter that information manually in Web Publishing Wizard.
