haproxy acl for url and url parameter

  • 772

I want to create an ACL in haproxy 1.6 that allows a particular url and url parameter ONLY when they both appear at the same time. For example:

example.com/url/of/page3?foo=bar

I am doing this already in the frontend section of my haproxy config:

acl whitelist path /url/of/page1
acl whitelist path /url/of/page2
acl whitelist path_beg /url/of/page3
block unless whitelist

How do I use url_param in combination with with path in my acl?

    • Not sure which version you're running, but, just as a note: AFAIK, the block directive is deprecated. Using this, gives you:

    The 'block' directive is now deprecated in favor of 'http-request deny' which uses the exact same syntax. The rules are translated but support might disappear in a future version.

    • It still works, but it might get removed in the future.

    • Regarding your question:

      • Just set up another ACL:

        acl url_param urlp(foo) bar

        This tests the first, and only the first url param against the name foo and the value bar, and evaluates to TRUE or FALSE.

      • So, after this, check for the results via:

        http-request deny unless whitelist url_param
