The following section provides a summary of functions performed by Posting Acceptor and the concepts behind those functions. This includes authenticating content publishers, processing a content post after it is received, managing content reposting failure, and creating mapping modules.
Built as an ISAPI application, Posting Acceptor accepts HTTP-based "POST" requests that contain a TargetURL for the incoming content. Posting Acceptor then parses the URL to a base that matches a hosted site, which is determined by querying the configured mapping modules until one succeeds. The remainder of the URL is assumed to be subdirectories of the matched/hosted URL. The incoming files are then deposited into the appropriate directory selected by the module.
Posting Acceptor takes content posts from any client conforming to the rules outlined in the HTTP multi-part/form-data method (RFC 1867), including Netscape Navigator (with the use of a form on the server). Further posting options are also supported if the client code is Microsoft WebPost API based, for example, Web Publishing Wizard and any other applications using the ActiveX Upload control.
