NP, let's stick to a generic example then, redacted down to the bare minimum

backend st-min-url
     # log request rate per distinct url+ip(v4/6)
     stick-table type binary len 8 size 1g expire 2m store http_req_rate(1m)

backend dc
     # works perfectly as expected
     http-request track-sc0 hdr_ip(x-forwarded-for) table st-min
     # need url32+hdr_ip(x-forwarded-for) here, as src is another haproxy
     http-request track-sc1 url32+src table st-min-url

As documented at https://docs.haproxy.org/2.4/configuration.html#4.2-http-request%20track-sc1 supports the <key> sample expression.

In the code use the "url32+src" the full_hash which is not exposed as sample function, afaik.

How about to try to use `hdr_ip(x-forwarded-for),base32` or something similar?

You can take a look into the reg-tests for some more inspiration :-)

     # send tracked sc-hour variables to core
     http-request set-header X-HA-Min-Rate-URL %[sc_http_req_rate(1)]
     # whatever backend

Hope this clarifies, haproxy -vv output follows, however any version will do

haproxy -vv

    As this is a quite generic question please send us the following info's.

    * haproxy -vv
    * your config, reduced and without any sensible data
    * A more detail explanation what exactly you want to do and what does
    not work.
