Bug 607408

Description of problem:

When trying to download Cobbler loaders with 'cobbler get-loader', it attempts to access the URL http://mdehaan.fedorapeople.org/loaders/README directly and not using the standard 'http_proxy' environment variable.

Version-Release number of selected component (if applicable):

5.3.0

How reproducible:

Always

Steps to Reproduce:
1. Block direct access to the internet and use a proxy.
2. Set the http_proxy environment variable correctly.
3. Run 'cobbler get-loader'
  
Actual results:

Expected results:

[root@satellite cobbler]# cobbler get-loaders
task started: 2010-06-24_125343_get_loaders
task started (id=Download Bootloader Content, time=Thu Jun 24 12:53:43 2010)

[... some kind of success here ...]

Additional info:

I would have thought that urlgrabber obeyed proxy configuration - maybe this needs to be pushed upstream or a different web library used.
