What is the best way to track marketing campaigns (using IIS / asp.net 2.0)

Microsoft IIS (latest)
asp.net 2.0


Hi

How can we track (numerous) separate marketing campaigns using IIS and
asp.net (2.0)?

(We are trying hard to AVOID having to set up a new directory for
every single marketing campaign...
so what is the best way to do create trackable URLs?)


So for example if we publish a marketing URL (in say a printed
newspaper) of

"www.ourdomain.com/xyzabc"

....then if the directory "/xyzabc" does not exist on our server, it
will generate a 404 error, right?

Now at present, the URL is then redirected to the page
"www.ourdomain.com/movetonewsite.aspx" , which then
redirects the user to the splash (i.e. welcome) page URL, which is:

"www.ourdomain.co.uk/splash-page.aspx?MovedTo=NewSite"

The problem is that SOMEHOW we need to get the "xyzabc" bit added to
the URL so that our
marketing people can track it.
i.e. ideally we would like it to be referred on to a URL such as:

"www.ourdomain.co.uk/splash-page.aspx?
MovedTo=NewSite&referrer=www.ourdomain.com/xyzabc"

or better:

"www.ourdomain.co.uk/splash-page.aspx?
MovedTo=NewSite&referrer=xyzabc"


Is there some clever way of to stuffing the referrer into the URL that
the 404 error throws
so that our marketing system (WebAbacus from Foviance) can readily
track it?

- Can anyone help?
- What do other people do on other sites ?

Many thanks
