Most likely reason, I think, is that your module is registered at a wrong place during configuration, and that's why it's not being called. To make sure your filter is called you should register it at HTTP_AUX_FILTER_MODULES list in the config file of your module. Alternatively, you may consider using the NGX_HTTP_SUBREQUEST_IN_MEMORY flag to ngx_http_subrequest(). This will allow you to get a response body in a post subrequest callback, without writing any response body filters. See src/http/modules/ngx_http_ssi_filter_module.c for a usage example, it's used to implement the "set" parameter of the "include" SSI command (see http://nginx.org/en/docs/http/ngx_http_ssi_module.html for docs). -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx-devel mailing list nginx-devel@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx-devel
