HOW Check Url Parametr and Redirect with Nginx rewrite

Question

I want to check if a parameter is present in a url in nginx and then rewrite.

How can i do that?

my code is here and not work !

if ($arg_loc != "") { rewrite ^(/search/.*)$ $1? permanent; }

UPDATE : i want redirect any url that ends with loc=number to the parent url ! for arabic and enlgish characters

EG :

http://website.com/search/node/item123/loc=33

i want redirect to

http://website.com/search/node/item123/

or

http://website.com/search/node/عربیک/loc=55

should be :

http://website.com/search/node/عربیک

Your example URL has no query arguments, therefore your if code cannot work. — Tero Kilkanen, Nov 10 at 21:49
Please clarify your issue. Does the URL you want to redirect contain query arguments or not? If it has query arguments, then your if approach is correct. If not, then you need to match on the URL path. — Tero Kilkanen, Nov 11 at 17:49

There is no query parameters in your examples. It's just an url, so you could use rewrite.

Something like that:

rewrite "^(/search/node/[^/]+)/loc=\d+$" $1 permanent;

P.S. I would strongly recommend to use keyword redirect instead of permanent until you're 1000% sure that redirect works as it should.

@BijanZand, what do you mean? Just put redirect instead of permanent. This will do 302 redirect instead of 301. The problem with permanent is, well, it's permanent and if you make a mistake you'll have hard time to remove that permanent redirect from your browser.

@BijanZand well \d stand for digits. You'll need \w or [a-z0-9] I guess. Anyway, make yourself familiar with regular expressions.
