New Revision: 1604934
URL: http://svn.apache.org/r1604934
Log:
Re-working the fix for http://issues.apache.org/bugzilla/show_bug.cgi?id=56653
I rollback addition of HostMapping class (reverting most of r1604319)
I will work on an alternative solution that should be easier to backport to
Tomcat 7.
(This revert temporarily breaks support for Aliases, per comment 2 in BZ 56653.
The alternative solution will fix it.)
