Hello list, I'm currently trying to migrate our stack from haproxy 1.7 to 2.0 and hit an issue with device detection.
We are using 51-Degrees for device detection. Our haproxy-1.7 instances are built with the 51-degrees v3.2.10 branch, the relevant config looks like this: global ... 51degrees-data-file /path/to/51Degrees-LiteV3.4.trie 51degrees-property-name-list IsMobile frontend www ... http-request set-header X-IsMobile %[51d.all(IsMobile)] This works as expected, the header X-IsMobile is set to either 'True' or 'False', depending on the device type. The same config with haproxy-2.0.9 built with the latest 51-Degrees branch v220.127.116.11 does not work. The X-IsMobile header is set to '1' unconditionally, i.e. for both mobile and desktop devices. If I replace the 51d.all fetch method with the 51d.single converter, it works: frontend www ... http-request set-header X-IsMobile %[req.fhdr(User-Agent),51d.single(IsMobile)] Again, the header is set to either 'True' or 'False' as expected, depending on the UA. Is this a problem with my config, a known issue, or am I missing something else? Best regards Florian
