Extended Apache Programming Interface (EAPI)
Apache 1.3.9 and later are built with an extended set of Apache APIs. This means that Apache 1.3.9 and later
expects these EAPIs to be built into any DSO they call. This EAPI feature is included in Apache so that a
DSO can be used by either Apache or WebWise, since WebWise requires EAPI for its SSL functionality.
