> mod_python is not able to invoke APR Optional Functions.  There are
> some cases however where this could be of great benifit.
> For example, consider writing an authentication or authorization handler
> which needs to determine SSL properties (even if to just answer the
> simple question: is the connection SSL encrypted).  The normal way of
> looking in the subprocess_env for SSL_* variables does not work in those
> early handler phases because those variables are not set until the fixup phase.
> The mod_ssl module though does provide both a ssl_is_https() and
> ssl_var_lookup() optional functions which can be used in earlier
> phases.  For example look at how mod_rewrite calls those; using
> the APR_DECLARE_OPTIONAL_FN and APR_RETRIEVE_OPTIONAL_FN
> macros.
> I can see how it might be very hard to support optional functions in
> general because of the C type linkage issue, but perhaps a select few
> could be coded directly into mod_python.
