Hello, Is there a chance to test if a "$arg_variable" (empty value) exists? The problem: "if" condition returns "false". URL: http://example.com/?variable nginx.conf: location / { if( $arg_variable ) { rewrite ^.*$ /other-location; } } Thanks a lot Marcus Posted at Nginx Forum: http://forum.nginx.org/read.php?2,224860,224860#msg-224860
