Hello,<br><br>Thanks, Pete, for the response. <br>I aplogize for not making my question clear. We are researching a caching and prefetching system for HTTP (from the client side). In order to test performance, we need to have the Internet Explorer request its HTTP GETs from our functions, instead of its server. Writing our own HTTP server is possible, but how would we get the IE to contact it when making a GET request?<br><br>Many Thanks,<br><br>Ami Tavory<br><br>
