How to serve files based on the accept-language header? I know that the header_regexp directive can be used for request matching by regular expression, but the selection of a language follows a list of preferred locales, like the example below.
An example of a list of accepted languages, sent by the browser:
accept-language: en-US, en;q=0.9, pt-BR;q=0.8, pt;q=0.7
In that request, the semantic is: "The order of preference is English US, if not present, try the Portuguese BR ". The server can select a default language, let’s say English, if any of the requested languages are supported.
The request matchers can be done like:
@english {
header Accept-Encoding *en-US*
file {
try_files /en_US/{path}
}
}
@portuguese {
header Accept-Encoding *pt-BR*
file {
try_files /pt_BR/{path}
}
}
… But I don’t know how to elaborate the selection logic according to the list of languages from the accept-language header.
