Hi all,
I have configured haproxy using the below configuration. No matter
what URL I browser to I always receive a HTTP 200 response to my
browser. If I comment out the ACL and three monitor lines from the
frontend configuration, normal behaviour is resumed. I have that gut
feeling that I have done something obviously wrong, but I can't spot
it :)
Where am I going wrong with this? I assume that haproxy captures
requests to /checkuri and sends back HTTP 200 when at least 2 back end
servers are up (which they are, I can see the requests coming into
them) and 503 when one or more is down. Otherwise, all other requests
are passed directly to the back end servers. It seems to be
intercepting whatever URI I request via GET and returns HTTP 200 OK,
nothing reaches the back end servers when the monitor URI is
configured.

lee than 2 backend servers
