Hi, Was it considered and if not how feasible would it be to expand match groups defined in the regex pattern in the output when using map_reg
i.e. your map file contains lines like this (CrMo)/(\d+)\.(\d+)\.(\d+)\.(\d+) Chrome\ Mobile,\2,\3,\4,\5 and you use in haproxy config http-request add-header UA %[hdr(User-Agent),map_reg(maps/uas,UNKNOWN)] I’m looking to build a haproxy compatible map file from https://raw.githubusercontent.com/ua-parser/uap-core/master/regexes.yaml <https://raw.githubusercontent.com/ua-parser/uap-core/master/regexes.yaml> https://raw.githubusercontent.com/ua-parser/uap-core/master/docs/specification.md <https://raw.githubusercontent.com/ua-parser/uap-core/master/docs/specification.md> Cheers Will
