AFAIK, the "name" attribute of a form tag really has no meaning and is
never transmitted to the server. On a normal HTML page, if you want to
send an extra bit of data you use a element.

1. In server-side code, use Microsoft.ServerXMLHTTP
2. I don;'t think this is possible due to security restrictions. What
are you trying to accomplish?

I'm not sure what your point is ... how does this help the OP accomplish

<<<<<<<<<<<

If you are doing simulations then one tool that is indispensible is
www.fiddlertool.com

With this running use a browser to perform a Form post you want to emulate.
You can now check the recorded session in the tool an you'll see what you
need to reproduce.

If you noticed from the example Evertjan gave you when the form method is a
POST the set of field values should be sent as the entity body of the
request, IOW a string encoded as URL search section is passed as the
paremeter of the send function.

Hence your code should look more like:-

Set xml = Server.CreateObject("MSXML2.ServerXMLHTTP")

strURL = "http//host.domain.com/search.asp?WCI=getPage"

strDat = "IsPortfolio=" & _
"&DEL=" & _
"&PropertyID=" & _
">YP=0" & _
"&PAGE=2" & _
"&PER=5" & _
"&RestrictSearch=" & _
"&StyleSheet=" & _
"&STYPE=0" & _
"&Exit=" & _
"&GID=422" & _
"&CURRENCY=GBP"

xml.Open "POST",strURL, False
xml.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
xml.Send strDat

Note that any values that you might concatenate into the data needs to be
urlencoded,

BTW, are you sure the form post actually results in an XML response?

Re: Simulate form post from Server Side

Hi Anthony,

Yes, definitely XML coming back.

The example:

javascript:document.SearchForm.PAGE.value='2';document.Searc hForm.submit()

was provided as a template example to me from the server owner. I could
simply do this and it would work fine. But then I would have to transform
the XML at the client side and I want it all on the server side.

Doing the above, ie. setting PAGE=2 from the client side does not seem to be
working when issued from the server side. Trouble is, it is very difficult
to work out why it doesn't work. I just get an empty page back.

Barry.

1) Install fiddler.
2) Build a VBScript file to emulate POST (use XmlHttp not ServerXmlHttp).
3) With fiddler use suppliers example of making post.
4) Use VBScript file to make the post.
5) In fiddler compare POSTs made by the two approaches
6) Adjust VBScript until its requests matches the suppliers example
7) Tweak script to use ServerXMLHTTP and check it still works
8) Install code into ASP.
