From 34db944be2559e39052c73af44af681cfcfd1e05 Mon Sep 17 00:00:00 2001
From: Joe Orton <jorton@apache.org>
Date: Thu, 3 Jun 2004 10:16:12 +0000
Subject: [PATCH] Fix links and update content in introduction.  Update page
 content to reflect that mod_ssl in 2.0 doesn't actually provide the most of
 the backwards-compat hooks; leave it as a guide for migration.

-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.</p>   
+mod_ssl mostly provides a superset of the functionality of all other
+solutions, so it's simple to migrate from one of the older modules to
+mod_ssl. The configuration directives and environment variable names
+used by the older SSL solutions vary from those used in mod_ssl;
+tables are included here to give the equivalents used by mod_ssl to
+allow easy migration. .</p>

 <section id="configuration"><title>Configuration Directives</title>
-<p>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
-compatibility is provided only for Apache-SSL 1.x and mod_ssl 2.0.x.
