NGINX: strip querystring in rewrite

Question

I'd like to make a 301 rewrite to the sites's index without any querystring. Like this:

http://example.com/anypage.asp?anyvar=anyvalue

To:

http://example.com/

Here's a real example:

http://atipico.com.br/conteudo.asp?P_categ=23

I am trying to follow this: http://wiki.nginx.org/NginxHttpRewriteModule#rewrite

(The commented are my attempts):

location ~ /conteudo\.asp(.*)$ {
    #rewrite ^ / permanent;
    #rewrite ^ /? permanent;
    #return 301 /;
    #return 301 /?;
    #if ($args) { return 301 /; }
}

It always rewrites to http://atipico.com.br/?P_categ=23

Any ideas?

Solution

This is the best rule I found and it is working to me:

rewrite ^/content /? permanent;

Meaning, rewrite all requests:

• starting in the root of the domain (^/)

• than followed by "content"

• to the root (index) of the site (/)

• removing all query strings it might have (?)

• and show a 301 redirect in the headers.

I guess that's it.

rewrite ^ /? permanent; works fine. Did you clear browser cache or try with another web browser?

[Admin]

Yes I had to clear browser cache for updates to have effect, didn't think this would be the case but tried it after reading @quanta comment and fixed my issue

Adding as a reference for OP: wiki.nginx.org/HttpRewriteModule#rewrite It will explain more details about the ? notation which drops the arguments.
