nginx location regexp for query string

Question

I want to redirect anything that comes directly to my server with perticuler query string to other location in same domain.

If user comes to

http://www.mydomain.com/?abc=js9sd70s

I want to redirect it to

http://www.mydomain.com/otherpath/?abc=js9sd70s

the query string ?abc=js9sd70s should be the same to new url.

Please suggest nginx config file.

I have tried most of the alternative for below code. by keeping '\' before ? and = sign.

        location ~ /?abc=.* {
                rewrite ^/(.*)$ http://www.mydomain.com/otherpath/$1 permanent;
        }

Please suggest me this location change.

Short answer, try this configuration:

location = / {
    if ( $arg_abc ) {
        rewrite ^ /otherpath/ permanent;
    }
}

Yes it redirected www.mydomain.com/?abc=js9sd70s to www.mydomain.com/otherpath/?abc=js9sd70s but now It is trying to redirect www.mydomain.com/otherpath/?abc=js9sd70s again and again, and it is not getting completed. Thanks for this help

can I put special check for ?abc is at domain root, then and only this redirection rule applies? like in this case www.mydomain.com/?abc=js9sd70s should redirected but www.mydomain.com/otherpath/?abc=js9sd70s should not be.

The rule above working only in domain root, use: location = / { documentation: wiki.nginx.org/HttpCoreModule#location

ok, Do I need to separate location /otherpath/ from location / in nginx config file? till now I have just one segment location / { #rewrite code } in config.

Please! Be carefull! location / and location = / it's a different locations! Read documentation first.
