can you add a parameter to the URL dynamically?

[tonynoriega]

we currently use a parameter on one of our links to just track what type of applications we are processing:

reason=new
reason=upgrade
reason=downgrade

and those are hardcoded into the link itself, and we store those parameters in a dbase for reporting

i.e.: www.example.com/application.aspx?reason=new

if someone was coming to our site via referral, say another site www.exampleB.com could i somehow code into that page to say:

if referral is 'www.exampleB.com'

add reason=exampleB

to the URL parameter string..

or replace "new" with "exampleB" in the string?

my knowledge of cookies is very limited, but that sounds like i would have to put a cookie on the users browser to make that stick with them through the application process? which is 15 pages long.

Yes you could do something like that with javascript easy enough I would think.

I'm not sure of what technology you are using (VB, C#) but you can query the referrer string on the landing page with Request.ServerVariables("HTTP_REFERER")

After filtering out the TLD you could then use a simple redirect to the target page. But you could also store the info in a session variable or cookie if you prefer.
