HTTP Request Forwarding in Classic ASP

[Mr Jen Withers]

Hey - Iam not sure if this is even possible with the limited API in classic ASP, but I need to find a way to forward a HTTP post request to a given URL. I need to do this to avoid a cross domain scripting issue where I cant get the target users to change their security settings. The client server is using IIS5 on windows2000 server so iam assuming I have no .net. The only other way of achieve this task instead of using classic ASP or .net is to use a console style CGI maybe - but id rather not rely on this! Thanks for any help in advance - Mike

You can propagate the post parameters into some hidden form fields (using server side scripting) of a form with an action specifying the target URL and submit the form in an onload event.

If you are talking about having the server forward a post request, you may be able to do something like this. My VBScript is kinda rusty, so expect a bug or two: <% Dim postData Dim xmlhttp 'sample form-POST data postData = "data=100" 'setup form post object 'we use the XML HTTP object Set xmlhttp = server.CreateObject("MSXML2.ServerXMLHTTP") 'replace with the server you would like to post to 'make sure "POST" is capitalized xmlhttp.Open "POST","http://my.target.server/target.asp",false 'set header with Content-Type rule for a typical form post xmlhttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded" 'send data in key=value pairs xmlhttp.send(dataToSend) 'write out return response from POST Response.Write xmlhttp.responseXml.xml 'destroy the http object Set xmlhttp = nothing %> If you are talking about just taking the browser post point to a differant location, if it's the same server, just use: Server.Transfer ("newlocation.asp", true)
