initial cache request gets all headers removed
----------------------------------------------
Key: MAGNOLIA-2215
URL: http://jira.magnolia.info/browse/MAGNOLIA-2215
Project: Magnolia
Issue Type: Bug
Components: cache
Affects Versions: 3.5.8, 3.5.7, 3.5.6, 3.5.5, 3.5.4
Environment: Magnlia 3.5.8, Tomcat 6.0.16, Java 1.6.0_04-b12
Reporter: Philippe Marschall
Assignee: Boris Kraft
Priority: Blocker
If a request is made to the cache filter and it's response is not yet cached
then all HTTP headers set previously by servlet filters are removed from the
response. For all subsequent requests the HTTP headers set by servlet filters
are preserved.
We are aware that HTTP headers are not cached but this is a different issue. We
explicitly set them in servlet filters for every request including cached ones.
The bug is in the following method in the class
_info.magnolia.cms.cache.CacheResponseWrapper_
{code}
public void resetBuffer() {
super.reset(); // BUG
if (cachingStream != null) {
cachingStream.reset();
}
cachingWriter = null;
status = SC_OK;
}
{code}
The problem is the invocation of the wrong superclass method (reset instead of
resetBuffer). This method in invoked by the jsp template renderer when it does
a forward.
{code}
public void resetBuffer() {
super.resetBuffer(); //FIXED
if (cachingStream != null) {
cachingStream.reset();
}
cachingWriter = null;
status = SC_OK;
}
{code}
