Hi, I wanted to add that since v1.5-dev11, there are the urlp_* matches which significantly help for matching URL params. I just added urlp_val to match an integer value this morning when reading this thread, however as with all other ACL integer values, it only supports unsigned values.
A few points below.

In fact haproxy is already able to perform some limited processing on POST data right now (eg: balance url_param check-post). We did not want to go further before reworking the ACL engine. Now that it's been done, I think it would be great if someone would engage in this, I mean, duplicate the urlp_* work into postp_* to perform post parameter extraction. And it would even allow us to stick on such parameters at no extra cost. It should really be easy to do, I can provide some help if someone wants to do it. Of course this would be limited by the request size, but that's already the case for the check-post. So any volunteers ? Willy
