Package: adzapper
Version: 20050316-1
Severity: wishlist
Tags: patch
The attached patch contains documentation and a small patch to adzapper and
adzapper.wrapper to support proxying with Apache2. This has the advantage of
being IPv6 friendly. Maybe this could be added to adzapper itself as it's
only a small patch.
Probably works with Apache 1.3 as well but since I haven't tested that I
only changed the package dependency for Apache 2.

+
+Alternatively, you can also use adzapper with Apache2. This has the advantage of
+being IPv6 compatible. To do this, make Apache2 load mod_proxy and mod_redirect
+and configure it as follows:
+
+ProxyRequests On
+RewriteEngine On
+RewriteLock /var/lock/apache2/rewrite-adzapper
+RewriteMap adzap prg:/usr/bin/adzapper.wrapper
+
+Order deny,allow
+Deny from all
+Allow from localhost
+RewriteRule ^proxy:(.*)$ proxy:${adzap:$1|$1} [L]
+
+
+Also, edit the new "NO_CHANGE_VALUE" configuration variable and set it to NULL:
+NO_CHANGE_VALUE="NULL".
