It was nearly that, you just forgot to name the headers on which the match had to be performed :-)

 acl toto-acl hdr(host) -i www.toto.com  acl test-acl hdr(host) -i www.test.com  acl bar-acl url_sub bar

 use_backend    toto    if toto-acl
 use_backend    test    if test-acl 
 use_backend    bar     if bar-acl

 default_backend default

I generally suggest to name ACLs with something more explicit, such as "host-toto" and "url-bar" as it will make it easier to debug your configs.

I'm currently in the process of completing the documentation. It also gives a very quick overview of HTTP (most notably differences between keepalive and close), and defines a little bit of vocabulary because I noticed that the old doc was very confusing. The new one should be far better in this respect.

BTW, Florian, please ensure that you are running version 1.3 (preferably between 1.3.12.4 and 1.3.14). The ACLs and content switching does not exist in version 1.2.
