+Subject: [PATCH] SiteAccess: Make VirtualHostMonster support IPv6
+
+from https://bugs.launchpad.net/zope2/+bug/699865 :
+
+VirtualHostMonster does not work with IPv6 named hosts.
+
+In case of such rewrite configuration:
+
+RewriteRule (.*) http://10.0.243.129:9280/VirtualHostBase/https/[%{SERVER_ADDR}]:4080$1 [L,P]
+
+When SERVER_ADDR is fd00::74ba VirtualHostMonster dies with:
+
+Traceback (most recent call last):
+  File "/eggs/Zope2-2.12.14-py2.6-linux-x86_64.egg/ZPublisher/BeforeTraverse.py", line 145, in __call__
+    meth(*(container, request, None)[:args])
+  File "/eggs/Zope2-2.12.14-py2.6-linux-x86_64.egg/Products/SiteAccess/VirtualHostMonster.py", line 154, in __call__
+    host, port = host.split(':')
+ValueError: too many values to unpack
+
+This is because IPv6 addresses contain ":" in them.
