Disable `redirect prefix` for `stats uri` in HAProxy

  • 772

In HAProxy (1.5) I have this rule to redirect all requests to a canonical domain:

redirect prefix https://domain.tld code 301 unless { hdr(host) -i domain.tld }

This works fine. However, I also have stats enabled (stats uri /haproxy-stats). For these I would like to disable the redirect as I need to access specific haproxy machines (they are behind a DNS round-robin) through their own host name.

Is there any way of configuring HAProxy in such a way?

  1. This can be done using an ACL rule:

    acl url_stats path /haproxy-stats
redirect prefix https://domain.tld code 301 unless { hdr(host) -i domain.tld or url_stats }

    Using an anonymous ACL works too:

    redirect prefix https://domain.tld code 301 unless { hdr(host) -i domain.tld } || { path /haproxy-status }

    However, it turned out to be not needed at all as HAProxy doesn't apply redirect rules to the stats url; probably I had an old 301 redirect cached.
