Double URL encoding of upstream file requests

[jaygooby]

When requesting files for zipping, if the url of the requested file is url-encoded, then the mod_zip module double-encodes the URL, resulting in a 404 from the upstream proxy. Here's a request to zip a single file that will fail due to URL encoding:

- - /flv/contains%20space.flv contains space.flv

The error log shows the upstream proxy being asked for /flv/contains%2520space.flv rather than /flv/contains%20space.flv

A simple workaround for this is to not url-encode spaces and use + instead:

- - /flv/contains+space.flv contains space.flv

However, this is only suitable when your files contain alphanumerics and spaces. You'll still probably have issues with characters like &, # etc.

Problem between keyboard and chair - looks like I didn't have the most recent version compiled in to nginx :(
