  <title>Bug 808292 - Implement path-level host-source matching to CSP (redirects)</title>

/* Description of the test:

 * First, we try to load a script where the *path* does not match.

 * Second, we try to load a script which is allowed by the CSPs

 * script-src directive. The script then gets redirected to

 * an URL where the host matches, but the path wouldn't.

 * Since 'paths' should not be taken into account after redirects,

 * that load should succeed. We are using a similar test setup

 * as described in the spec, see:

 * http://www.w3.org/TR/CSP11/#source-list-paths-and-redirects
