Oh sorry, I at least should say what the main key to DSO support for mod_ssl
was: Instead of patching in SSL-things into the Apache core now a totally
generic API extension is patched in (the apache.patch file now contains mainly
non-SSL stuff). This extended API provides mainly the following three
additional features:
Four additional module hooks, a generic low-level hook mechanism and a generic
context mechanism. All three thing together provide a way to _loosely_ couple
mod_ssl into the Apache core code instead of couple it via direct symbol
references (the big NO-NO for DSO). This way even inter-module communication
is possible: For instance mod_log_config's SSL support is now loosly coupled
to mod_ssl, too. This way mod_log_config has not even to be linked against
SSLeay ;-)
