  Added files:                 
    /loncom/rewrites	loncapa_rewrite_on.conf loncapa_rewrite_off.conf 

  Modified files:              
    /doc/loncapafiles	webserver.piml loncapafiles.lpml 
    /loncom	loncapa_apache.conf 
  Log:
  - Bug 5925. 
  - Support for rewriting of http:// to https:// for external web requests
    if mod_ssl and mod_rewrite enabled.  Default is: Rewrite off.
  
  - webserver.piml
    - Update description to accommodate additional distros.
    - Error message generated if Apache config file is missing tailored to
      distro.
    - Compare LON-CAPA config file to rewrite: http:// -> https:// with
      default files (rewrite Off and rewrite On); report if neither matches.
   
  - loncapafiles.lpml 
    - Only need /etc/httpd/conf directory for CentOS/Red Hat/SL/Fedora
    - Default files for rewrites Off and rewrites On in loncom/rewrites
  
  - loncapa_apache.conf
    - Include conf/loncapa_rewrite.conf  to support rewrite.
