SVN commit 1083276 by adawit:

- Prevent all cache related header directives from being sent through the customHttpHeader 
  meta-data sent to the http ioslave.

  This should fix the intermittent issues with missing images or partial rendering of pages, 
  specially when navigating back in history.
