Setting headers after response was committed with website tree
--------------------------------------------------------------
Key: MAGNOLIA-2685
URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-2685
Project: Magnolia
Issue Type: Bug
Components: core
Affects Versions: 4.1
Environment: winstone
Reporter: Grégory Joseph
Assignee: Philipp Bärfuss
Fix For: 4.1
This is currently visible with Winstone. For some reason, the servlet response
is already committed when we try to add headers. (from the cache or gzip
filters, possibly)
This might even only be occuring currently with the quickstart page.
This results in a blank page.
