I am trying to modify the information in the post array.  In PHP I could simply modify the post array by using $_POST[key] = "new value";

I do not know how to change the post array in classic ASP (it is not asp.net, just plain asp).  

Thanks for any help.

Object doesn't support this property or method: 'Form'

I think you may not be able to easily update the request.form like you do with $_POST in php.
Request.form is a collection and probably would require a special method to update it, where as $_POST is basically just a glorified global array.

yes there is a way to this in asp.
put the array in a session variabele and on the next page put it in a var and than you can make changes in the array

session("arr") = arrSomething

on next page
dim arr
if isArray(session("arr")) then
  arr= session("srr")
end if

well, i'm using a big classic asp application that is quite large.  I need to go into the post data as soon as it is sent to the server to make sure that no malicious code has been put in the post data.  I do not know exactly how this large application utilizes the post data so i need to manipulate the post data.  

Setting a session variable won't work in this case.

Well, the post-data (as in Request.Form) is read-only. That makes sense, as it only registers what has been posted.

You can catch the posted data in your own variables
<%myvar = Request("fieldname")%>

and then of course you can change the value of myvar.

you cannot modify the post data so what i wanted to do was impossible.
