Are you sending values to a page or receiving values from a page via HTTP POST? When doing so, it's often necessary to verify the values are being sent correctly and that the field names being used are the ones you expect. If you're an XMod user, this is useful if you're using the
tag or tag or if you're receiving values into your form via the tag. Of course, POSTing values isn't an XMod-only activity and you may find use for this script elsewhere in your development activities.
Here is a copy-and-paste snippet of code you can put on your server to determine what is being passed to a page via HTTP POST. Simply copy the code and put it into an ASPX page on your server. Then, set your XMod <redirect> target to that page. It will display the POSTed values at the top of the page, followed by a list of everything sent to the page, which can also be useful when debugging things. This works with any call to the page, so it isn't just for XMod.
Here's the code:
<%@ Page Language="VB" ContentType="text/html" ResponseEncoding="iso-8859-1" %>
<%@ Import Namespace="System" %>
<%@ Import Namespace="System.IO" %>
<%@ Import Namespace="System.Web" %>
<%@ Import Namespace="System.Net" %>

For i as integer = 0 to Request.Params.AllKeys.Length - 1

lblOutput.Text &= "<strong>" & strKey & "</strong> " & Request.Params(strKey) & "<br />"
Next
For i as integer = 0 to Request.Form.AllKeys.Length - 1
Dim strKey as string = Request.Params.AllKeys(i)
lblPostedValues.Text &= "<strong>" & strKey & "</strong> " & Request.Form(strKey) & "<br />"

End Sub
