-Here 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 Apache-SSL -(from where mod_ssl were originally derived in 1998), Red Hat's commercial Secure Web -Server (which is based on mod_ssl), Covalent's commercial Raven SSL Module (also based on mod_ssl) -and finally C2Net's commercial product Stronghold (based on a -different evolution branch named Sioux up to Stronghold 2.x and based on -mod_ssl since Stronghold 3.x).
+This page covers backwards compatibility between mod_ssl and other +SSL solutions. mod_ssl is not the only SSL solution for Apache; four +additional products are (or were) also available: Ben Laurie's freely +available Apache-SSL (from +where mod_ssl were originally derived in 1998), Red Hat's commercial +Secure +Web Server (which was based on mod_ssl), Covalent's commercial Raven SSL Module (also based on +mod_ssl) and finally C2Net's (now Red Hat's) commercial product Stronghold (based +on a different evolution branch named Sioux up to Stronghold 2.x and +based on mod_ssl since Stronghold 3.x).-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.
+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. .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 Table 1. Currently full backward -compatibility 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.
+The mapping between configuration directives used by Apache-SSL +1.x and mod_ssl 2.0.x is given in Table +1. The mapping from Sioux 1.x and Stronghold 2.x is only partial +because of special functionality in these interfaces which mod_ssl +doesn't provide.
