Problem with keep-alive and use_backend

[Kari Lavikka]

Hi

I'm evaluating HAProxy and it looks very promising. However, I noticed 
odd behavior and didn't find any documentation regarding it.

I have the following configuration:

frontend irc-galleria
       bind            .......
       mode            http
       use_backend     chatserver      if { path_beg /chatserver }
       use_backend     suggestsearch   if { path_beg /suggestSearch }
       default_backend lighttpd-suomi

Both chatserver and suggestSearch are Jettys. Now the problem is: If I 
browse a chatserver or suggestSearch url and continue to another page 
that should be fetched from lighttpd-suomi, I'll get 404 errors from 
Jetty. For some reason haproxy evaluates ACLs only on the initial 
request in a keep-alive session. I found two "solutions" to this problem 
- either disable keep-alive in browser or add "option httpclose" to 
chatserver and suggestSearch backends.

Do I have a misconfiguration or is this a feature/bug? Thanks!
