As an aside, should the documentation extract below actually read:
acl local_dst hdr(Host) -i localhost
^
^
i.e. is the name of the header case sensitive? In my attempts to work this
out I think that I had to use 'Host' rather than 'host' before it worked.
4.2. Alphabetically sorted keywords reference
---------------------------------------------
This section provides a description of each keyword and its usage.
acl <aclname> <criterion> [flags] [operator] <value> ...
Declare or complete an access list.
May be used in sections : defaults | frontend | listen | backend
no | yes | yes | yes
Example:
acl invalid_src src 0.0.0.0/7 224.0.0.0/3
acl invalid_src src_port 0:1023
acl local_dst hdr(host) -i localhost
See section 7 about ACL usage.

Subject: Matching URLs at layer 7
I'm confused over the behaviour of the url criteria in layer 7 acls.
If I have a definition of the form:
acl xxx_host hdr(Host) -i xxx.example.com
then something like this works fine:
use_backend xxx if xxx_host
If I try something like this:
acl xxx_url url_beg -i http://xxx.example.com
use_backend xxx if xxx_url
then it fails.
I've tried:
acl xxx_url url_sub -i xxx.example.com
acl xxx_url url_dom -i xxx.example.com
Same result....I'm missing something obvious here, I just can't see it :-(
My ultimate goal is to have:
use_backend xxx if xxx_url xxx_host
which I think makes sense for a browser request that has not been fiddled
with...if I could test it I would be able to find out!
Any insights appreciated :-)
Cheers
andrew
