    ISAPI DLLema


    Hey all,

    I am trying to take form info from a web page, assemble an XML textstream,
    send it off to another company's server, then parse and display the XML response
    to a new web page. I am assuming there is a standard Winsock-like ISAPI
    extension that does this, but have had trouble finding it. Does this gem
    exist?

    I'm also wondering if I should do the parsing in ASP and just call the socket
    extension, or create an ActiveX DLL that will handle the parsing and calling
    of the socket.

    Any answers, full or partial, would be greatly appreciated! Will consider
    naming my firstborn after you.

    Thanks,
    justin

    As part of the MSXML library installed with IE 5 there is also an
    XMLHTTPRequest object which allows for transmits and reception of strings to
    and from an HTML server. It is designed for client-server communication, but
    based on your description should work within an ASP server-server scenario
    (really client server anyway)

    Excerpt from MSDN Library:

    XMLHttpRequest Object

    ----------------------------------------------------------------------------
    ----

    The XMLHttpRequest object provides client-side protocol support for
    communication with HTTP servers.

    Remarks

    A client computer can use the XMLHttpRequest object (Microsoft.XMLHTTP) to
    send an arbitrary HTTP request, receive the response, and have the Microsoft
    XML Document Object Model (XMLDOM) parse that response.

    This object is integrated with MSXML to support sending the request body
    directly from, and parsing the response directly into, the MSXML Document
    Object Model objects. When combined with the support for XSL, the
    XMLHttpRequest component provides an easy way to send structured queries to
    HTTP servers and efficiently display the results with a variety of
    presentations.

    MS Claims it won't scale for server side use and that there may be problems
    using it in that scenario. Seems to work fine in my quick tests however...
