Will,
I'm just curious what you can't understand in the current
documentation, which is, as a remeinder:
--------------8<----------------------
url_param(<name>[,<delim>])
This extracts the first occurrence of the parameter <name> in
the parameter string of the request and uses the corresponding
value to match. Optionally, a delimiter can be provided. If not
then the question mark '?' is used by default.
A typical use is to get sticky session through url for cases
where cookies cannot be used.
Example :
# match http://example.com/foo?PHPSESSIONID=some_id
stick on url_param(PHPSESSIONID)
# match http://example.com/foo;JSESSIONID=some_id
stick on url_param(JSESSIONID,;)
--------------8<----------------------
I can't see how much simpler I could have done it.
Any feedback and thought is welcome!
