Is there a way to make nginx rewrite the GET request parameters while
configured as a reverse proxy. e.g. if nginx receives a request GET /
foo.html?abc=123 , can nginx rewrite it to GET /foo.html?abc=456 (nginx
admin specifies 123 to be changed to 456) and then do a proxy pass to
the origin server.
I did a test run with using $args on the lines of
rewrite ^ http://example.com/ permanent; }
as explained at http://wiki.nginx.org/HttpRewriteModule. However, this
seems to work only for when nginx is the web server. It tries to fetch
the content from the local nginx html folder.
Please provide inputs.
