Thank you for all your help.
I've fixed the problem now in configuring the backends to just answer
with a index.php file as default, for every unspecific request. That
seems to solve the problem for now.

What URL does haproxy use exactly to check the service?
Is it the realm + the url part or something else?
Just to be sure to test the correct option.
Hi Sebastian
If you are just using the "check" option for the backends, then the
health check is considered successful if a successful TCP connection
can be established on the IP/port specified for the backend.
This is often not a good indicator of health for HTTP applications,
and for those you can use "option httpchk" to do actual HTTP requests.
This option may take any of these forms:
option httpchk - Does an HTTP/1.0 GET for the URI "/"
option httpchk <uri> - As above, but you can specify the URI to use
instead of "/"
option httpchk <method> <uri> - As above, but you can specify the HTTP
method as well (GET, POST, etc.)
option httpchk <method> <uri> <version>, As above but you can also
specify the version, i.e. if you want to use HTTP/1.1 instead. To use
this you probably need to send the HTTP Host: header as well, you can
see in my example below how that's done.
In all cases, the health check is considered successful if the HTTP
status code returned from the backend is 2xx or 3xx.
The last form is typically the most useful. Let's say your app is
www.example.com <http://www.example.com> and you decide that
retrieving the URI /test is the way to determine if it's healthy or
not, you would then use the following in the backend definition:
option httpchk GET /test HTTP/1.1\r\nHost:\ www.example.com
<http://www.example.com>
If you still have questions, please post the backend definition from
your config file.
