ere we talk about backward compatibility to other SSL solutions. As you
perhaps know, mod_ssl is not the only existing SSL solution for Apache.
Actually there are four additional major products available on the market: Ben
Laurie's freely available <a href="http://www.apache-ssl.org/">Apache-SSL</a>
(from where mod_ssl were originally derived in 1998), RedHat's commercial <a
href="http://www.redhat.com/products/product-details.phtml?id=rhsa">Secure Web
Server</a> (which is based on mod_ssl), Covalent's commercial <a
href="http://raven.covalent.net/">Raven SSL Module</a> (also based on mod_ssl)
and finally C2Net's commercial product <a
href="http://www.c2.net/products/stronghold/">Stronghold</a> (based on a
different evolution branch named Sioux up to Stronghold 2.x and based on
mod_ssl since Stronghold 3.x).

<p>
The idea in mod_ssl is mainly the following: because mod_ssl provides mostly a
superset of the functionality of all other solutions we can easily provide
backward compatibility for most of the cases. Actually there are three
compatibility areas we currently address: configuration directives,
environment variables and custom log functions.
<h2><a name="ToC1">Configuration Directives</a></h2>
For backward compatibility to the configuration directives of other SSL
solutions we do an on-the-fly mapping: directives which have a direct
counterpart in mod_ssl are mapped silently while other directives lead to a
warning message in the logfiles. The currently implemented directive mapping
is listed in <a href="#table1">Table 1</a>. Currently full backward
compatibilty is provided only for Apache-SSL 1.x and mod_ssl 2.0.x.
Compatibility to Sioux 1.x and Stronghold 2.x is only partial because of
special functionality in these interfaces which mod_ssl (still) doesn't
provide.

<h2><a name="ToC3">Custom Log Functions</a></h2>
When mod_ssl is built into Apache or at least loaded (under DSO situation)
additional functions exist for the <a
href="../mod_log_config.html#formats">Custom Log Format</a> of <a
href="../mod_log_config.html">mod_log_config</a> as documented in the Reference
Chapter. Beside the ``<code>%{</code><em>varname</em><code>}x</code>''
eXtension format function which can be used to expand any variables provided
by any module, an additional Cryptography
``<code>%{</code><em>name</em><code>}c</code>'' cryptography format function
exists for backward compatibility. The currently implemented function calls
are listed in <a href="#table3">Table 3</a>.
