Awsome Jason thanks for that little lesson , do you have any info that
talks about that , after changing to your mime type that works
everywhere , pages load now just missing the jpeg's .... So I guess
anytime your asked to block jpeg's then using the mime type is the
best way to go , I have always been using stuff like "match protocol
http url "*.jpg | *.jpeg" and get hit or miss results sometimes they
block sometimes they dont.. Jason is the man..
Thanks again Jason
