2653: # The Apache SSL configuration used by LON-CAPA is contained in
2654: # two files: sslrewrite.conf and loncapassl.conf.
2655: #
2656: # Starting with LON-CAPA 2.12, name-based virtual hosts are used
2657: # with port 443. The default virtual host (i.e., the one listed
2658: # first) is for the server's standard hostname, and that is the one
2659: # which will respond to client browser requests for https:// pages.
2660: #
2661: # Accordingly, a system administrator will need to edit the config
2662: # config file to include paths to a signed SSL certificate (public),
2663: # chain (public) and key (private) pem files. The certificate should
2664: # have been signed by a recognized certificate authority ((e.g.,
2665: # InCommon or Let's Encrypt).
2666: #
2667: # The sslrewrite.conf file contains the rewrite configuration for
2668: # the default virtual host. The rewrite rules defined are used to
2669: # allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served
2670: # http://, in order to support vertical alignment of mimetex images
2671: # (one of the options for rendering Math content); (b) allow requests
2672: # for certain URLs (external resource, and syllabus, if external URL
2673: # used) to be served http:// to accommodate the use of iframes which
2674: # would otherwise result in browser blocking of mixed active content.
2675: #
2676: # The loncapassl.conf file contains the configuration for the
2677: # "internal" virtual host, which will respond to requests for https://
2678: # pages from other LON-CAPA servers in the network to which the node
2679: # belongs. The ServerName is internal-<hostname> where <hostname>
2680: # is the server's hostname. There is no need to create a DNS entry
2681: # for internal-<hostname>, as LON-CAPA 2.12 automatically performs
2682: # the required hostname to IP mapping.
2683: #
2684: # Requests to /raw on the "internal" virtual host require a valid
2685: # SSL client certificate, signed by the certificate authority
2686: # for the LON-CAPA network to which the node belongs.
2687: #
2688: # The configuration file to which the contents of sslrewrite.conf
2689: # and loncapassl.conf will be written will have either been identified
2690: # when &chkapachessl() was run, or if no files were found with
2691: # existing rewrite blocks, then a candidate file will be chosen
2692: # from the .conf files containing VirtualHosts definitions.
2693: # If there is more than one suitable candidate file, the system
2694: # administrator will be prompted to select from the available files.
2695: #
2696: # If there are no files containing VirtualHosts definitions, then
2697: # <VirtualHost *:443> </VirtualHost> blocks will be appended to
2698: # the standard Apache SSL config for the particular distro:
2699: # ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf
