Can't this be backported to the 3.6 branch ?

> -------------------------------------------------------------------

> Key: MAGNOLIA-2472
> URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-2472
> Project: Magnolia
> Issue Type: Bug
> Components: cache
> Affects Versions: 3.6.3
> Environment: WinXP, JDK 1.5
> Reporter: Jackson Nicolas
> Assignee: Jan Haderka
> Fix For: 4.0
>

> I have a paragraph using Freemarker and an action paragraph class.
> I've recently decided to add a page redirect. I do attempt the page
> redirect by accessing response object via WebContext. Everything works
> fine until the redirect is actually performed.
> Please note: The redirect works fine when I disable the GZip Filter.
> My Code:
> WebContext ctx = null;
> if(MgnlContext.getInstance() instanceof WebContext)
> ctx = (WebContext)MgnlContext.getInstance();
> if(ctx != null) {
> try {
> HttpServletResponse response = (HttpServletResponse)
> ctx.getResponse();
> if (!response.isCommitted()) {
> response.reset();
> response.sendRedirect(MgnlContext.getContextPath() +
> ContentUtil.getContentByUUID(ContentRepository.WEBSITE,
> redirectPage).getHandle() + "." +
> ServerConfiguration.getInstance().getDefaultExtension());
> }
> } catch (IOException ioe) {
> //TODO: handling
> }
> }
> The error:
> java.lang.IllegalStateException: Failure when attempting to set
> response header Content-Encoding: gzip
