I've been mainly relying on the user feedback on such (unsupported) usage. In theory, they *should* work with ngx.location.capture*. But there might be some knobs to resolve. I'm not sure and I cannot give you any details at this point. Sorry. Regards, -agentzh ___ nginx-devel mailing list nginx-devel@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx-devel
RE: subrequest error with http2
Hi, I'm aware 1.9.5 isn't supported yet and that SPDY is mentioned in the docs as non-working for certain API calls as well. However, we are have been using location.capture with SPDY for a while now and haven't seen any issues. Information on why and what issues are present is a little fuzzy (and searching only returns old stuff that some sources claim not to apply anymore), can you provide some details?

This is also why ngx_lua has so many advanced features :) Actually I quite like the fact that NGINX does not enforce a limited set of API for 3rd-party modules to use and 3rd-party module authors can almost always find their way to implement bold imaginations *grin* For the same reason, I'll hate to see that NGINX enforces a well defined ABI, BTW :) Regards, -agentzh ___ nginx-devel mailing list nginx-devel@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx-devel

The lua module deeply integrates into nginx internals (far beyond what we consider to be nginx modules API), and there is no surprise it's broken by the changes in nginx 1.9.5. -- Maxim Dounin http://nginx.org/ ___ nginx-devel mailing list nginx-devel@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx-devel
