  31. This page covers backwards compatibility between mod_ssl and other
  32. SSL solutions.  mod_ssl is not the only SSL solution for Apache; four
  33. additional products are (or were) also available: Ben Laurie's freely
  34. available <a href="http://www.apache-ssl.org/">Apache-SSL</a> (from
  35. where mod_ssl were originally derived in 1998), Red Hat's commercial
  36. <a href="http://www.redhat.com/products/product-details.phtml?id=rhsa">Secure
  37. Web Server</a> (which was based on mod_ssl), Covalent's commercial <a href="http://www.covalent.net/">Raven SSL Module</a> (also based on
  38. mod_ssl) and finally C2Net's (now Red Hat's) commercial product <a href="http://www.redhat.com/explore/stronghold/">Stronghold</a> (based
  39. on a different evolution branch named Sioux up to Stronghold 2.x and
  40. based on mod_ssl since Stronghold 3.x).</p>
  41.  
  42. <p>
  43. mod_ssl mostly provides a superset of the functionality of all the other
  44. solutions, so it's simple to migrate from one of the older modules to
  45. mod_ssl. The configuration directives and environment variable names
  46. used by the older SSL solutions vary from those used in mod_ssl;
  47. mapping tables are included here to give the equivalents used by mod_ssl.</p>
