This ticket covers the doc work required to create and publish a 2.4.57 version of the HTTP Connectors and Load Balancing guide.

• Create a copy of the existing 2.4.51 HTTP Connectors and Load Balancing guide and update the version number to 2.4.57.
• Ensure that any existing statements such as "From JBCS 2.4.51 onward" still read correctly or remove them altogether from the 2.4.57 doc.
• Ensure that any existing statements such as "In JBCS 2.4.51" are updated to "In JBCS 2.4.51 or later".
• Review and update if necessary all existing information for httpd deployments on RHEL 9 to ensure that it reads correctly for the 2.4.57 release.
