Displaying ServerVariables in IIS

A lot of admins use the phpinfo function to debug the headers the server gets when the site is requested.

You can do the same trick when you have no php on a windows server.

In ASP it is called ServerVariables.

Create a file with the asp extension in the root of the site with the following content:

<%
for each x in Request.ServerVariables
  response.write("<b>" & x & "</b> : " & Request.ServerVariables(x) & "<br>")
next
%>

When you request that file you will see all the variables in the Server environment.
