URL-Based Load Balancing

Question

I'm having a difficult time trying to configure load balancing on my CSM based on the URL entered. Here is my scenerio:
Two web servers (WebA & WebB), load balanced on a CSM. WebA & WebB have 90% the same content, so most traffic can be load balanced between them without a problem. The problem (for me anyway) comes in where WebA has certain web sites that WebB doesn't, and vice versa. So I need to load balance to both for 90% of the traffic, and point traffic to a particular server the other 10% of the time based on the URL entered.
Below is the test config I have so far (that doesn't work correctly), what I am trying for in this example is that any URL that contains /vhosts/ or /programs/ be directed to WebA, and any URL that contains /platform/ or /ssl/ be directed to WebB, and all other traffic be load balanced between the two evenly. (For testing purposes, the servers are being load balanced in "bridge-mode", in production they will be "routed-mode"....I did't want to go through the change controls to change the IP addresses for the test servers!).

Thanks for the reply Gilles....I've been out of the office for a while.
Well, right now nothing is working....except that all traffic is going to the default server farm assinged to the vserver. Here are the URLs I am testing with:
**************TEST A************
http://10.63.240.10/manual/vhosts/fd-limits.xml
http://10.63.240.10/manual/programs/apachectl.xml
**************TEST B************
http://10.63.240.10/manual/platform/ebcdic.xml
http://10.63.240.10/manual/ssl/ssl_compat.xml
***************BOTH****************
http://10.63.240.10/manual/howto/htaccess.xml
http://10.63.240.10/manual/howto/cgi.xml
When I try attaching to the first URL for example, here is the connection info (I trimmed it down so it will fit here):
MOSL1S1A#sh mod csm 2 real
real server farm Conns/hits
10.40.109.100 URL-POLICY-TEST 1
10.40.109.101 URL-POLICY-TEST 0
10.40.109.100 URL-TESTA 0
10.40.109.101 URL-TESTB 0
MOSL1S1A#
MOSL1S1A#sh mod csm 2 conn
prot vlan source destination
In TCP 605 10.47.10.10:3738 10.63.240.10:80
Out TCP 605 10.40.109.101:80 10.63.240.204:8820
I've tried changing the syntax on the URL statement in the map as such:
/manual/*
*/manual/*
/manual/
*manual*
/manual*
