Two Apache web servers

[Clay_Chappell]

All of my servers (HP-UX 11.23, IA64) have two different Apache web server products installed: hpuxwsApache and hpuxws22Apache. There is very little information out there about hpuxws22Apache.
What is the difference between these two products and are both really necessary?

The major difference between the hpuxwsApache and hpuxws22Apache is the version of Apache.
hpuxwsApache has Apache version 2.0
hpuxws22Apache has Apache Version 2.2

hpuxwsapache has been replaced by hpuxws22apache (Apache 2.2.8.08),which combines Apache with numerous popular modules from other Open Source projects and provides HP value-added features for HP-UX.

Refer "HP-UX Apache-based Web Server" release notes for details:

hpuxwsApache is part of a webserver suite that contains: Webserver, Tomcat, and Web Admin. If I remove hpuxwsApache, will hpuxws22Apache work properly with the remaining software products in the suite or must I remove the entire suite and upgrade with the latest HP-UX Apache-based Web Server v.3.x bundle?

Per HP
SMH has a dependency with wsApache.
Until this dependency is resolved and SMH is ported to ws22Apache, it will be necessary to run both versions of Apache.
Since there are security vulnerabilities with both versions, it will be necessary to upgrade wsApache to v2.0.63.01 and ws22Apache to v2.2.15.03
