Hi Marc,This dev is done in the current haproxy version. The keyword is "language", this is the documentation: language(<value[;value[;value[;...]]]>[,<default>]) Returns the value with the highest q-factor from a list as extracted from the "accept-language" header using "req.fhdr". Values with no q-factor have a q-factor of 1. Values with a q-factor of 0 are dropped. Only values which belong to the list of semi-colon delimited <values> will be considered. If no value matches the given list and a default value is provided, it is returned. Note that language names may have a variant after a dash ('-'). If this variant is present in the list, it will be matched, but if it is not, only the base language is checked. The match is case-sensitive, and the output string is always one of those provided in arguments. The ordering of arguments is meaningless, only the ordering of the values in the request counts, as the first value among multiple sharing the same q-factor is used. Example : # The "language" keyword must take the list of all language that # your load balanced web site support. The list of matched # language must contain all RTL languages. acl rtl req.fhdr(accept-language),language (de;es;fr;en;ar) ar use_backend rtl if rtl default_backend ltr
Shouldn't we need to provide a matching method (for example "-m str") ? In this case, the "language" documentation also needs to be updated. -- Cyril Bonté
