Hey Rommel,

one way to do that is to check Dr. Weitz's very own url-rewrite[1], a
Hunchentoot dependency, in particular ADD-GET-PARAM-TO-URL:

* (add-get-param-to-url "http://common-lisp.net/" "foo" "bar")
"http://common-lisp.net/?foo=bar"

* (add-get-param-to-url "http://common-lisp.net/index.html?frob=42" "foo" "bar")
"http://common-lisp.net/index.html?frob=42&foo=bar"

* (add-get-param-to-url "http://common-lisp.net/" "foo" "+")
"http://common-lisp.net/?foo=%2B"

Regards,
Victor.
