Here are two examples of what you could do with server variables.

HTTP_REFERER server variable can be used as a Dynamic Previous Page Hyperlink.

Paste this code into an asp file and you have an instant (Back Button).
Or add a graphic if you wish.

<a href="<%= Request.ServerVariables("HTTP_REFERER") %>">Previous Page</a>

Previous Page

HTTP_USER_AGENT server variable can determine the client browser type

<%=Request.ServerVariables("HTTP_USER_AGENT")%>

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)

Regarding these Server Variables you can always loop through them as well and show all of them which is very helpful when testing.

<table border="1" width="500" style="border-collapse: collapse"> 
<% 
For each item in Request.ServerVariables 
   Response.Write("<tr><td>" & item & "</td><td>") 
   Response.Write(Request.ServerVariables(item)) 
   Response.Write("</td></tr>" & vbCrLf) 
Next 
%> 
</table>

ASP (Active Server Pages) is a technology developed by Microsoft. Pages using ASP are primarily developed in JScript, or VBScript and are integrated into the HTML of your Web pages. The ASP code is compiled on-the-fly by the server and the resulting output is standard HTML. By using ASP, Web pages can be dynamic, full of ever-changing content, and browser independent.
