+# hide-tor-exit-notation: Header filter to remove the Tor exit node notation
+# in Host and Referer headers.
+#
+# Note: If Privoxy and Tor are chained and Privoxy is configured to
+# use socks4a, one can use http://www.example.org.foobar.exit/
+# to access the host www.example.org through Tor exit node foobar.
+#
+# As the HTTP client isn't aware of this notation, it treats the
+# whole string "www.example.org.foobar.exit" as host and uses it
+# for the "Host" and "Referer" headers. From the server's point of
+# view the resulting headers are invalid and can cause problems.
+#
+# An invalid "Referer" header can trigger "hot-linking" protections,
+# an invalid "Host" header will make it impossible for the server to
+# find the right vhost (several domains hosted on the same IP address).
+#
+# This filter removes the "foo.exit" part in those headers
+# to prevent the mentioned problems. Note that it only modifies
+# the HTTP headers, it doesn't make it impossible for the server
+# to detect your Tor exit node based on the IP address the request is
+# coming from.

# Revisions :
# $Log: default.filter,v $
+# Revision 1.30 2006/10/18 12:36:50 fabiankeil
+# google filter now cleans Google groups as well.
+#
+# Revision 1.29 2006/10/11 14:03:17 fabiankeil
+# Changed img-reorder regex to only move width
+# attributes if they are following at least one
+# whitespace. Fixes BR 1328455.
+#
+# Revision 1.28 2006/10/11 13:31:13 fabiankeil
+# Added Anduin Withers' js-annoyances fix
+# for not messing up escaped quotes. Fixes BR 999765.
+#
+# Improved blogspot filter to make it less likely that
+# the blogspot banner at the top of the page is missed.
+#
+# Revision 1.27 2006/10/08 17:00:51 fabiankeil
+# Modified webbugs filter to create a comment around the offending
+# image instead of removing it entirely.
+#
+# Adjusted regex to only match if there's at least one whitespace
+# before the width and height attributes. Makes it more likely that
+# they are indeed attributes, and not part of the value of another attribute.
+# Solves BR 1035587.
+#
+# Thanks to Martin Thomas for diagnosing the cause of the problem.
+#
# Revision 1.26 2006/10/06 18:06:16 fabiankeil
# Added header filter x-httpd-php-to-html
# and reverted another img-reorder whitespace
