You can't use sendfile if you have to scan file contents for a special byte. By writing a filter you may avoid reinventing the wheel and doing file reads yourself. Downside is that you have to write filter which is expected to work with a data stream, which is not always feasible. -- Maxim Dounin http://nginx.org/en/donation.html _______________________________________________ nginx-devel mailing list nginx-devel@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx-devel
