No it's not. Try:
http://www.mydomain.com.com/url?campaign=25&env=PRD

Easiest would be to make "url" some script in a language of your choice
that increments a counter stored in a database somewhere, and then prints
out a transaparent GIF (with the correct MIME type of course).
You might be able to speed it up a little by storing your count in a flat
file instead of a database, but then you'll need to worry about file
locking: to make sure that simultaneous writes to the file don't break
things. (With an SQL database, the SQL engine takes care of these little
intricacies itself.)
