Functionality Differences Between Apache 1.3 and 2.0

During the planning of my proxypot, a crucial decision came up about the version of Apache which was going to be used. There are major fundamental differences between Apache 1.3 and 2.0.

Apache 1.3 has the majority of current market share due to its greater length of existence. The 2.0 version is gaining in popularity. There are many advancements in Apache 2.0 that not only improve Apache performance, but also has flexibility for security enhancements. The table below illustrates the main differences between Apache 1.3 and Apache 2.0

Feature		Apache 1.3		Apache 2.0
IPv6 Capability		Unofficial Patches		Fully Supported
Multi-Processing Mudules/Threading		Less-scalable Multi-process model		Enhanced to support several models for better scalability
Build Configuration		APACI		GNU Autoconf
Server Configuration directives		Redundant directives		Streamlined to remove confusing
Platform Support (APR)		Limited and problematic		Expanded with Apache Portable Runtime
Multi-Protocol Support		None		Can create protocol modules
HTTP Proxy Support		HTTP 1.0		HTTP 1.1
Input/Output Filtering		None		Fully Supported
SSL Support OpenSSL's support		Unofficially supported		Supported through mod_sll, which uses OpenSSL's support

There are a handful of features Apache 2.0 version that enable you to accomplish important security tasks. The most notable are the advanced proxy capability, improved header manipulation with mod_headers, and finally input/output filtering. There is also a really cool feature of the Mod_Security module called Output filtering that is only available if you are using Apache 2.0. So perhaps Apache 2.0 will be deployed for the proxypot !
