- 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.
