Build simple ISAPI filter using ISA 2004 SDK.

Summary: I'm looking a c++ programmer who can write a simple ISAPI plugin using ISA 2004 SDK. The filter should use requested URL and rewrite it based on request from webservice I wrote. In general requested URL and all request details like client ip, authenticated username etc should be passed to webservice using POST in format similar to [login to view URL] details webservice will respond with different URL which should be then passed back to ISA for processing. Technical Summary: ISA 2004 SDK provide set of notifications after request is being received, notification you should use is SF_NOTIFY_ROUTING which will give you a WPX_FILTER_ROUTE structure. the url in contained within pszHost string and this value should be passed to webservice and modified with response.
