the best way for url-based balancing??

Hi to the list

I have been playing around with the haproxy configuration trying to find a way to balance the http traffic on my web cluster based on the url that clients are accesing.

I have seen on the haproxy source package a config file named "url-switching.cfg" which seems to do what I want but it does it in a "strange" way assigning a cookie when the url matchs with a regexpression and then balancing using that cookie. Maybe it´s enough for most of haproxy users but I´m trying to do it in a easier way so that developers on my department could modify the haproxy config without too much knowledge about how haproxy works or reg expressions.

So my question is....¿¿is there any other way to do url-based balancing with haproxy?? any clue about which directives I should look for in the documentation. I have been reading docs and haven´t found anything about url-based balancing (just the config url-switching.cfg that I mentioned before)

many thanks in advance for any help.
