Removing all GET parameters for redirect

Question

I want to redirect the following url to homepage using nginx

https://www.example.com/old.php?u=BUH09MrRGtnYWB2Nc5CGcX879Y6wqF5EDTij6vphybUekhzY0Qo%3D&b=5

The url above should redirect to https://www.example.com/

I am using the following rule

rewrite ^/old.php(.*)$ https://www.example permanent;

The redirect to homepage works but i see the

https://www.example.com/?u=BUH09MrRGtnYWB2Nc5CGcX879Y6wqF5EDTij6vphybUekhzY0Qo%3D&b=5

Instead of https://www.example.com/ in address bar

Answer 1

according to http://wiki.nginx.org/HttpRewriteModule#rewrite , you just need to add a ? at the end of the rewrite:

rewrite ^/old.php(.*)$ https://www.example? permanent;
