Disable / ignore / redirect URLs with query strings to reduce blog spam

Server NGINX
1

Hello all,

Is it possible to disable / ignore / redirect all URLs
with any query string? My site doesn’t use query strings,
and is suffering from blog spam links as described by
these folks:

How do I remove spam from my blog’s Google Blog Search results?

Google has the wrong (somewhat vulgar) URL for my site!

URL/Query String Spam - Poor Man’s Referer Spam?
http://www.dgibson.net/blog/article.cfm/articleid=7/URLQuery-String-Spam---Poor-Mans-Referer-Spam

This Apache .htaccess example <
http://briancray.com/2010/03/18/htaccess-hack-remove-url-query-strings/

removes all query strings like so:

RewriteEngine On
RewriteCond %{QUERY_STRING} !=“”
RewriteRule ^(.*)$ /$1? [R=301,L]

Can something similar be done in nginx? Also, might it be
better to simply return a 204 (or some other status code)
to reduce server load?

Sincerely,

Miles

This will not work for complex $uri which requires encoding.

    # OR
    # rewrite  ^  $uri  permanent;

Correct rewrite would be

      rewrite  ^(.*)  $1?  permanent;

($1 instead of $uri to make sure it will be properly escaped, and
“?” to avoid query string append).

}

Thanks so much, Igor & Maxim!

I went with:

server {
… some earlier directives
if ($args != ‘’) {
rewrite ^(.*) $1? permanent;
… more directives follow
}

and it works like a charm. Those blog spam links
will be gone in no time! Thank you!!

Sincerely,

Miles
