Configuration Ideas
|
|
|
|
Here are some theoretical configuration ideas that we could implement some
|
|
time. Note the naming convention: %Namespace.Directive. If you want one
|
|
implemented, give us a ring, and we'll move it up the priority chain.
|
|
|
|
%Attr.RewriteFragments - if there's %Attr.IDPrefix we may want to transparently
|
|
rewrite the URLs we parse too. However, we can only do it when it's a pure
|
|
anchor link, so it's not foolproof
|
|
|
|
%Attr.ClassBlacklist,
|
|
%Attr.ClassWhitelist,
|
|
%Attr.ClassPolicy - determines what classes are allowed. When
|
|
%Attr.ClassPolicy is set to Blacklist, only allow those not in
|
|
%Attr.ClassBlacklist. When it's Whitelist, only allow those in
|
|
%Attr.ClassWhitelist.
|
|
|
|
%Attr.MaxWidth,
|
|
%Attr.MaxHeight - caps for width and height related checks.
|
|
(the hack in Pixels for an image crashing attack could be replaced by this)
|
|
|
|
%URI.AddRelNofollow - will add rel="nofollow" to all links, preventing the
|
|
spread of ill-gotten pagerank
|
|
|
|
%URI.HostBlacklistRegex - regexes that if matching the host are disallowed
|
|
%URI.HostWhitelist - domain names that are excluded from the host blacklist
|
|
%URI.HostPolicy - determines whether or not its reject all and then whitelist
|
|
or allow all in then do specific blacklists with whitelist intervening.
|
|
'DenyAll' or 'AllowAll' (default)
|
|
|
|
%URI.DisableIPHosts - URIs that have IP addresses for hosts are disallowed.
|
|
Be sure to also grab unusual encodings (dword, hex and octal), which may
|
|
be currently be caught by regular DNS
|
|
%URI.DisableIDN - Disallow raw internationalized domain names. Punycode
|
|
will still be permitted.
|
|
|
|
%URI.ConvertUnusualIPHosts - transform dword/hex/octal IP addresses to the
|
|
regular form
|
|
%URI.ConvertAbsoluteDNS - Remove extra dots after host names that trigger
|
|
absolute DNS. While this is actually the preferred method according to
|
|
the RFC, most people opt to use a relative domain name relative to . (root).
