Nginx not returning custom error pages from if expression
I can replicate the problem when the $if statements are directly inside the server block, but it works correctly when they are inside a top-level location block. This worked for me:
location / { if ($args !~ ^$){ return 404; } if ($request ~* (^.*\?.*$)){ return 404; }}Of course, if you have other location blocks, you may need to include the rules there too.
