I got this to work:
use_backend %[path,lower,map_reg(/path/tofile)]
and with a map file containing:
^\/sebseb/
^\/test2/
and so on..
Only issue is the performance hit.. its going to do regex match with
path on each line in the map file.. :(
I'd prefer to find a function to replace path.. which could substract
the first part ^\/([^/])\/ - and then use \1 to match in map file..
But perhaps the map_reg isn't that expensive?

Hi guys,
I figured I could use map feature of 1.5, but I'm coming up short,
trying to change this:
use_backend %[req.hdr(host),lower,map(/path/tofile)]
To instead take a part of the uri.
I can't find any list of functions (such as hdr, hdr_end etc.) in the
docs :(
I figured I could use "something like" regrep instead of hdr(host)?

Hi guys,
we have a long list of backends (want to monitor each application on a
tomcat behind us) - and would like to use part of the url ( first part
between / / ) to identify the backend (in haproxy) to use.
so if we get a request for /sebseb/api/whatever - we'd like to use
backend named kki-sebseb.
we figure this should not be dangerous since haproxy seems fairly well
coded - so a request for something bogus, should just result in the
backend being invalid - and returning a 504 (we hope) ?
I can't seem to find any examples on the net.. and can't figure it out
from the haproxy 1.5 docs..
I was hoping any of you had some hints :)
