Request.ServerVariables
When a client requests a document from the server, IIS gathers some
information from both the client and from the server and about the file
being requested. This information is dumped into a collection known as
the Request.ServerVariables collection. You ASP program has
access to the collection, which is handy at times.
With the ServerVariables, you can obtain the client's browser information,
the referring URL, their username (if you have IIS security set to not
allow anonymous visitors), the URL being fetched, and a slew of other
informative bits of information.
A complete article dealing with the Request.ServerVariables collection
already exists on the site. It can be found at this URL.
You can see an example of the Request.ServerVariables collection being
used in an ASP app by reading this
article, which provides souce code for a dynamic content tree, so
your visitors know what pages they've visited on your site.
