Forum: NGINX Browser shows rewritten URL

Hi,

I need to rewrite
http://mysite:81/magento_mysite/abc
to
http://mysite:81/magento_mysite/?store=abc

I am able to do this using the .conf file. However, the browser shows 
the
rewritten URL and not the original.
Apache's mod_rewrite ensures that the browser shows the original URL and
not the rewritten one.

Is there some parameter I should be passing to avoid showing the new 
URL?

Thanks,
Yash

location = /magento_mysite/abc {
  return 301 /magento_mysite/?store=abc;
}
