  30 <p>
  31 Here we talk about backward compatibility to other SSL solutions. As you
  32 perhaps know, mod_ssl is not the only existing SSL solution for Apache.
  33 Actually there are four additional major products available on the market: Ben
  34 Laurie's freely available <a href="http://www.apache-ssl.org/">Apache-SSL</a>
  35 (from where mod_ssl were originally derived in 1998), Red Hat's commercial <a href="http://www.redhat.com/products/product-details.phtml?id=rhsa">Secure Web
  36 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)
  37 and finally C2Net's commercial product <a href="http://www.c2.net/products/stronghold/">Stronghold</a> (based on a
  38 different evolution branch named Sioux up to Stronghold 2.x and based on
  39 mod_ssl since Stronghold 3.x).</p>
  40
  41 <p>
  42 The idea in mod_ssl is mainly the following: because mod_ssl provides mostly a
  43 superset of the functionality of all other solutions we can easily provide
  44 backward compatibility for most of the cases. Actually there are three
  45 compatibility areas we currently address: configuration directives,
  46 environment variables and custom log functions.</p>

  54 <h2><a name="configuration" id="configuration">Configuration Directives</a></h2>
  55 <p>For backward compatibility to the configuration directives of other SSL
  56 solutions we do an on-the-fly mapping: directives which have a direct
  57 counterpart in mod_ssl are mapped silently while other directives lead to a
  58 warning message in the logfiles. The currently implemented directive mapping
  59 is listed in <a href="#table1">Table 1</a>. Currently full backward
  60 compatibility is provided only for Apache-SSL 1.x and mod_ssl 2.0.x.
  61 Compatibility to Sioux 1.x and Stronghold 2.x is only partial because of
  62 special functionality in these interfaces which mod_ssl (still) doesn't
  63 provide.</p>
