Static Modules vs Dynamic Modules

Support for a specific module can be statically linked into the httpd binary at compilation, by specifying it with a configuration option similar to "--enable-proxy", or the module can be loaded at runtime, if the Dynamic Shared Object (DSO)] capability is enabled.

It is preferable to use shared modules which are loaded as needed with the LoadModule directive.

If a module is compiled with the intention to load it dynamically, the corresponding "enable" compilation flag should carry the "shared" value (example "--enable-proxy=shared").

Dynamic Shared Object (DSO)

http://httpd.apache.org/docs/current/dso.html

Dynamic Shared Object (DSO) capability is enabled at compilation by using "--enable-so" option.
