2848: # The Apache SSL configuration used by LON-CAPA is contained in
2849: # two files: sslrewrite.conf and loncapassl.conf.
2850: #
2851: # Starting with LON-CAPA 2.12, name-based virtual hosts are used
2852: # with port 443. The default virtual host (i.e., the one listed
2853: # first) is for the server's standard hostname, and that is the one
2854: # which will respond to client browser requests for https:// pages.
2855: #
2856: # Accordingly, a system administrator will need to edit the config
2857: # config file to include paths to a signed SSL certificate (public),
2858: # chain (public) and key (private) pem files. The certificate should
2859: # have been signed by a recognized certificate authority ((e.g.,
2860: # InCommon or Let's Encrypt).
2861: #
2862: # The sslrewrite.conf file contains the rewrite configuration for
2863: # the default virtual host. The rewrite rules defined are used to
2864: # allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served
2865: # http://, in order to support vertical alignment of mimetex images
2866: # (one of the options for rendering Math content); (b) allow requests
2867: # for certain URLs (external resource, and syllabus, if external URL
2868: # used) to be served http:// to accommodate the use of iframes which
2869: # would otherwise result in browser blocking of mixed active content.
2870: #
2871: # The loncapassl.conf file contains the configuration for the
2872: # "internal" virtual host, which will respond to requests for https://
2873: # pages from other LON-CAPA servers in the network to which the node
2874: # belongs. The ServerName is internal-<hostname> where <hostname>
2875: # is the server's hostname. There is no need to create a DNS entry
2876: # for internal-<hostname>, as LON-CAPA 2.12 automatically performs
2877: # the required hostname to IP mapping.
2878: #
2879: # Requests to /raw on the "internal" virtual host require a valid
2880: # SSL client certificate, signed by the certificate authority
2881: # for the LON-CAPA network to which the node belongs.
2882: #
2883: # The configuration file to which the contents of sslrewrite.conf
2884: # and loncapassl.conf will be written will have either been identified
2885: # when &chkapachessl() was run, or if no files were found with
2886: # existing rewrite blocks, then a candidate file will be chosen
2887: # from the .conf files containing VirtualHosts definitions.
2888: # If there is more than one suitable candidate file, the system
2889: # administrator will be prompted to select from the available files.
2890: #
2891: # If there are no files containing VirtualHosts definitions, then
2892: # <VirtualHost *:443> </VirtualHost> blocks will be appended to
2893: # the standard Apache SSL config for the particular distro:
2894: # ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf
2895: # for SuSE/SLES, and default-ssl.conf for Ubuntu.
2896: #
2897: # Once a file is selected, the contents of sslrewrite.conf and
2898: # loncapassl.conf are compared with appropriate blocks in the file
2899: # and the user will be prompted to agree to insertion of missing lines
2900: # and/or deletion of surplus lines.
