Apache: The Definitive Guide, 3rd Edition

Choosing Modules

Inclusion of modules is done by uncommenting (removing the leading #) lines in Configuration. The only drawback to including more modules is an increase in the size of your binary and an imperceptible degradation in performance.^[12]

The default Configuration file includes the modules listed here, together with a lot of chat and comment that we have removed for clarity. Modules that are compiled into the Win32 core are marked with “W”; those that are supplied as a standard Win32 DLL are marked “WD.” Our final list is as follows:

AddModule modules/standard/mod_env.o
