https://issues.apache.org/bugzilla/show_bug.cgi?id=44679 covers most of
the discussion - just skip over the various rants.

You'll be better off with 5.5.28. I'm fairly sure more cookie handling
patches were ported across.

If the cookie is set and used from within your app, you *should* be
fine. If you have a case where that doesn't appear to be working let us
know.

If the cookie is set by a third party app, then that app may need to
change to be compliant with the cookie specs.
