Remove query string from url

Question

We have a magento store which appends a query to our URL when you change Magento store views on the frontend.

i.e. http://www.domain.com/?___store=uken

Is there a way to remove the ?___store=uken with NGINX configuration? Say remove any query beginning with ?___store=. I'm very new to server config & nginx in particular.

Answer 1

If you need to delete the querystring __store= from the URL you have to clear the variable $args and then rewrite the main location.

Try to use this rule to delete the querystring from the url:

location / {
    set $args '';
    rewrite ^/(.*)$ /$1 permanent;
}

or if you have a website url like: http://www.mystore.com/shop/index.php?__store=en you can rewrite the new location with:

location /shop {
    set $args '';
    rewrite ^/shop/(.*)$ /shop/$1 permanent;
}

Answer 2

If you want to remove a specific parameter from multiples:

if ($request_uri ~ "([^\?]*)\?(.*)_=([^&]*)&?(.*)") {
    set $original_path $1; 
    set $args1 $2; 
    set $unwanted $3; 
    set $args2 $4; 
    set $args ""; 

    rewrite ^ "${original_path}?${args1}${args2}" permanent;
}
