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.
