How to make Nginx redirect from site.com/%40userto site.com/@user
I write the following condition , but there is no redirect. It seems to me that this is because of the % sign , it needs to be escaped somehow, because when I remove it and leave it just 40 , the redirect works for I tried to look for how to escape % , but there is nothing sensible. Maybe I'm digging in the wrong direction? rewrite ^/%40(.*)$ /@$1 permanent; rewrite ^/40(.*)$ /@$1 permanent;site.com/40user

Answer 1

locationand rewritefor matching use the request URI in a normalized form, i.e. already after decoding the text given in the form %XX.
In its original form, the request can be found in $request_uri. There it will be entirely (with arguments).

if ($request_uri ~ "^/%40(.*)$") {
    return 301 /@$1;
}
