How do I POST data to a remote URL in Classic ASP?

Question

I need to POST data to a url in the middle of a script.

1. User fills out form:
2. Form submits to process.asp: I need to POST data to a 3rd Party integration at this point.
3. process.asp finishes and directs user to thank you page.

I'm not sure why everybody else is posting ASP.Net solutions when you specifically said you're using ASP "classic."

Something like this should work. I didn't write the code; I found it elsewhere. But the MSXML2.ServerXMLHTTP object is what you want to use if you don't want to purchase something commercial.

function getHTML (strUrl)
    Set xmlHttp = Server.Createobject("MSXML2.ServerXMLHTTP")
    xmlHttp.Open "GET", strUrl, False
    xmlHttp.setRequestHeader "User-Agent", "asp httprequest"
    xmlHttp.setRequestHeader "content-type", "application/x-www-form-urlencoded"
    xmlHttp.Send
    getHTML = xmlHttp.responseText
    xmlHttp.abort()
    set xmlHttp = Nothing   
end function 

You might need to add some error-handling code to that for use in a production environment. I believe that object throws errors if it gets a 404 or timeout error. You'll need to "trap" them ASP-style (yuck) by setting On Error Resume Next before the .Send and then examine the ASP error object to see if there was a problem.

Good luck!
