I have a Wt wthttpd Server running two threads or instances of the server,
I want each URL to be on its own backend, and will have other URLs in this
same configuration;
I just keep it simple here with one running two threads; but how do I do
this?
This link shows the basic setup for Wt wthttpd
http://redmine.webtoolkit.eu/projects/1/wiki/Using_HAProxy_as_a_reverse_proxy
As you can see it creates the thread using a Prefix, so I want to attach
the URL to this Prefix.
I tried to AND the two like this:
acl is_domain_com_0 hdr_end(host) -i domain.com
use_backend domain_com_be_0 if is_domain_com_0 AND url_sub wtd=wt-8080
This is the warning I get
[ALERT] 146/224731 (4249) : parsing [/etc/haproxy/haproxy.cfg:30] : error
detected while parsing switching rule.
where line 30 is this line:
use_backend domain_com_be_0 if is_domain_com_0 AND url_sub wtd=wt-8080
