Urllib downloader doesn't handle HTTP 302 redirects

[sunnyps]

Some HTTP proxies will respond to requests with 302 redirects, and it seems Package Control's urllib downloader doesn't handle those.

By default urllib uses an HTTPRedirectHandler instance to handle redirects, but it's missing from the list of handlers in urllib_downloader.py setup_opener:

package_control/package_control/downloaders/urllib_downloader.py

Line 257 in b9de5ff

def setup_opener(self, url, timeout):

Package Control.sublime-settings.txt

package_control.log

Just noticed that #1502 is essentially the same issue, so feel free to close this.
