Whose Fault Is This?

Nick Parker

Ok, on a project I am working on I have three separate pages that can submit to the same search results page, based on what page they come from I give them a message at the top of the search results page identifying their search criteria. To the point here I couldn't remember the exact ServerVariable that would give me the referer. I remembered that I wrote a quick script to list all keys and their values from the Request.ServerVariables object. I quickly ran it and found that I wasn't able to find the key I was looking for. This required me to do some (see below) research. I quickly found all I needed Request.ServerVariables("HTTP_REFERER"). Why the hell it doesn't show up when you do something like this I don't understand.

<%
dim i

For each i in Request.ServerVariables
Response.Write "" & i & "" & ": " & _
Request.ServerVariables(i) & " "

Next
%>

Note from above: --Some Research: 5 seconds wasted doing a search on Google. :mad: Nick Parker

Request.ServerVariables("HTTP_REFERER") only shows up when there is a referer. If you type the address in, you won't get one, so it won't show up.

Again I feel like there is an error in that statement. You see HTTP_REFERER is a valid key regardless of whether or not there is an associated value to it, when you cycle through the Server.Variables you will see several keys that don't have a value at that time, however that doesn't mean their key isn't show, that is the problem I am talking about.[
