Hi,

I have created a public proxy with nginx but when i download files like  
“proxy.\*\*\*\*\*.com/?[url=google.com/images/logo\_sm.gif](http://url=google.com/images/logo_sm.gif)” the filename  
“logo\_sm.gif” it’s not save in browse as the real name but with the  
name: “download”.

I need a rewrite rules that rename the filename with $args of url.  
Eg:  
site.tld/?url=proxed.tld/file.zip

the file.zip will be downloaded as “download” name, not with file.zip  
name. So i need a rule that rename the file with another with:  
site.tld/?url=proxed.tld/file.zip&=filename.zip

This is very easy for who know rewrite of nginx, i searn a lot of  
combination but i loss only time…
