mod_xhtml_neg performs content-negotiation for XHTML documents conforming to Appendix C of the XHTML 1.0 specification.
This module for the the Apache HTTP server gives it the ability to correctly negotiate content types for XHTML documents. Without negotiation, these would be sent as text/html. For browsers that support XHTML as an XML document, the content can (and should) be sent as application/xhtml+xml. See the W3Cs technical note for details.
Also see RFC 3236 for some of the technicalities of correctly negotiating XHTML documents.
One solution thats been seen around the web in a few places is to use the Apache mod_rewrite module to sniff the Accept: header in HTTP requests. This is crude but will work most of the time. See an example of this at Greytower Technologies.
This Apache module does similar negotiation, but with the following advantages:
- It can correctly handle relative quality values for different content-types based on the browsers Accept header
- It will correctly send Vary headers and a unique ETag header for each response type, thus ensuring proxy caches will work correctly
- Can perform character set negotiation based on the Accept-Charset header, taking into account the default character sets defined in RFC 2616 and RFC 3023
- Can perform negotiation based on XHTML profiles using the optional "profile" parameter in the Accept header.*
Will correctly degrade caching for HTTP 1.0 proxies
Profiles are XML namespaces that refer to the XHTML variants, such as XHTML Basic, XHTML Mobile Profile, and so on. The profile parameter was introduced in section 8 of RFC 3236.

ITVal is a decision-diagram based query engine for testing and verifying iptables firewalls.

Because firewalls can be very complicated, it is often difficult to know whether your firewall is correctly configured to protect against various attacks.

ITVal allows the system administrator to quickly and easily verify that the firewall setup satisfies a set of security properties expressed as queries.

Queries are specified in a simple English-like language that is very easy to use. Advanced firewall techniques, such as NAT and stateful filtering, are supported.
