ASP/VBScript Form Post Handling

[xernoth]

Hi there,

Just a quick question. I'm more familiar with C# and ASP.NET but need
to use ASP/VBScript for a quick project.

I have a form that uploads content to a server not managed by us. When
the form is filled in and posted, the response from the server is an
XML response. However when that happens, I'm not longer at my asp
page, I'm redirected the XML response URL that's managed by the third
party server.

I have two questions are a result:
1) I understand I can use XmlHTTP to simulate a form and post that
using XmlHttp.Send String. However, the form that uploads content is
quite complex. It contains 4 type=text input fields, 1 textarea field,
and a type=file field.
How would I specify all this in the XmlHttp.Send String? More
specifically, how would I specify the type=file field? When using a
proxy trace application to manually intercept my post, the type=file
field looks like this:
Content-Disposition: form-data; name="file1"; filename="C:
\mediaexample.wmv"
Content-Type: video/x-ms-wmv

2) Is there anyway to specify a html form in the XmlHttp.Send? So
instead of having to build a string with all the form information,
just reference the form name and Send that instead?

Any ideas would be appreciate. For the record, I've done extensive
browsing, and although I've come across useful information, nothing
that quite answers my dilemma. If I'm overlooking the obvious, please
let me know.

Thanks.

Why not just do
Set http = Server.CreateObject("msxml2.ServerXMLHTTP")
http.Open "POST", "...url..."
http.Send Request.Form
???

That is, just "forward" the entire contens of the form to the remote site??
