%20 need to replace with -

[omverma]

Dear All,
                    My website is being hit by some urls that is not served
properly by nginx due to some characters like %20.

http://www.abc.com?param=test (Works fine)

http://www.abc.com?param=test%20again (Do no work)
it should be something like this http://www.abc.com?param=test-again


I want to replace %20 with - (Dash). Please suggest me best regex for the
same.


Thanks,
Om
