Hi, if i have a url ending with a / how can i rewrite the request before  
go to the proxy so the ending slash is dropped?

i want [www.host.com/uri/](http://www.host.com/uri/) to be [www.host.com/uri](http://www.host.com/uri)

rewrite ^(.\*)/$ $1;

This is because in nginx you cannot substitute part of the url. The  
replacement string is always considered as a whole new url. So this will  
not work:

rewrite /$ “”; # DOESN’T WORK
