Compatibility

Content

If you are applying a new release of HTTP Server for i, applying a group PTF containing a new level of Apache, you will need to take into account potential incompatibilities.


Differences between releases of HTTP Server for i
HTTP Server on IBM i 7.1 is based on Apache version 2.2.11
HTTP Server on IBM i 7.2 and i 7.3 is based on Apache 2.4.x
Group SF99713 level 11 and below is based on Apache 2.4.2
Group SF99713 level 12 and above is based on Apache 2.4.12
For compatibility issues when moving from older releases to IBM i 7.2, please see this doc for reference.

Differences between levels of Apache on HTTP Server (powered by Apache)
Starting with Apache 2.0.47, there are no significant compatibility differences between the available levels of HTTP Server (powered by Apache).
Always be sure to load the latest PTFs to get the most current fixes for HTTP Server for i.


To determine the level of Apache on your system enter, for example:
STRTCPSVR SERVER(*HTTP) HTTPSVR("APACHEDFT" '-V')
Note: The command was entered on a IBM i 7.2 system with group SF99713 level 12 installed.


You will see details similar to the following.
