Hello, mod_negotiation supports the 'prefer-language' environment variable. As this page [1] says "If it exists and contains an appropriate language tag, mod_negotiation will try to select a matching variant.". It would be nice if mod_include could pass this variable along with sub-requests in the 'include' element, so that included files always have the correct language. Thanks for considering, Rob [1] https://httpd.apache.org/docs/2.4/content-negotiation.html
