 For an overview how these are related and chained together have a look at the

 page in README.dsov.{fig,ps}. It contains overview diagrams for those data

 SSL_EXPERIMENTAL_xxxx variables, except if SSL_EXPERIMENTAL_xxxx_IGNORE

 is already defined. Currently the following features are experimental:

   o SSL_EXPERIMENTAL_PERDIRCA

     The ability to use SSLCACertificateFile and SSLCACertificatePath

     in a per-directory context (.htaccess). This is provided by some nasty

     reconfiguration hacks until OpenSSL has better support for this. It

     should work on non-multithreaded platforms (all but Win32).

   o SSL_EXPERIMENTAL_PROXY

     The ability to use various additional SSLProxyXXX directives in

     oder to control extended client functionality in the HTTPS proxy

   process_rec->pool->user_data. The ssl_pphrase_Handle_CB() and 

   ssl_config_global_* () functions have an extra parameter now - 

   "server_rec *" -  which is used to retrieve the SSLModConfigRec.

 o Properly support restarts, allowing mod_ssl to be added to a server

   that is already running and to change server certs/keys on restart

 o Various performance enhancements

 TODO

 o Cleanup ssl_engine_io.c !!

 o Port all remaining code (code inside #if 0...#endif blocks)

 o Do we need SSL_set_read_ahead()?

 o Enable use of MM, SHMCB and SHMHT.

 o Enable SSL extensions (ssl_engine_ext.c)

 o add configure check for SSL_set_cert_store to support per-dir

   SSLCACertificate{File,Path}

 o the ssl_expr api is NOT THREAD SAFE.  race conditions exist:

   -in ssl_expr_comp() if SSLRequire is used in .htaccess

    (ssl_expr_info is global)

   -is ssl_expr_eval() if there is an error

    (ssl_expr_error is global)

 o SSLRequire directive (parsing of) leaks memory
