2576: # The Apache SSL configuration used by LON-CAPA is contained in
2577: # two files: sslrewrite.conf and loncapassl.conf.
2578: #
2579: # Starting with LON-CAPA 2.12, name-based virtual hosts are used
2580: # with port 443. The default virtual host (i.e., the one listed
2581: # first) is for the server's standard hostname, and that is the one
2582: # which will respond to client browser requests for https:// pages.
2583: #
2584: # Accordingly, a system administrator will need to edit the config
2585: # config file to include paths to a signed SSL certificate (public),
2586: # chain (public) and key (private) pem files. The certificate should
2587: # have been signed by a recognized certificate authority ((e.g.,
2588: # InCommon or Let's Encrypt).
2589: #
2590: # The sslrewrite.conf file contains the rewrite configuration for
2591: # the default virtual host. The rewrite rules defined are used to
2592: # allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served
2593: # http://, in order to support vertical alignment of mimetex images
2594: # (one of the options for rendering Math content); (b) allow requests
2595: # for certain URLs (external resource, and syllabus, if external URL
2596: # used) to be served http:// to accommodate the use of iframes which
2597: # would otherwise result in browser blocking of mixed active content.
2598: #
2599: # The loncapassl.conf file contains the configuration for the
2600: # "internal" virtual host, which will respond to requests for https://
2601: # pages from other LON-CAPA servers in the network to which the node
2602: # belongs. The ServerName is internal-<hostname> where <hostname>
2603: # is the server's hostname. There is no need to create a DNS entry
2604: # for internal-<hostname>, as LON-CAPA 2.12 automatically performs
2605: # the required hostname to IP mapping.
2606: #
2607: # Requests to /raw on the "internal" virtual host require a valid
2608: # SSL client certificate, signed by the certificate authority
2609: # for the LON-CAPA network to which the node belongs.
2610: #
2611: # The configuration file to which the contents of sslrewrite.conf
2612: # and loncapassl.conf will be written will have either been identified
2613: # when &chkapachessl() was run, or if no files were found with
2614: # existing rewrite blocks, then a candidate file will be chosen
2615: # from the .conf files containing VirtualHosts definitions.
2616: # If there is more than one suitable candidate file, the system
2617: # administrator will be prompted to select from the available files.
2618: #
2619: # If there are no files containing VirtualHosts definitions, then
2620: # <VirtualHost *:443> </VirtualHost> blocks will be appended to
2621: # the standard Apache SSL config for the particular distro:
2622: # ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf
2623: # for SuSE/SLES, and default-ssl.conf for Ubuntu.
2624: #
2625: # Once a file is selected, the contents of sslrewrite.conf and
2626: # loncapassl.conf are compared with appropriate blocks in the file
2627: # and the user will be prompted to agree to insertion of missing lines
2628: # and/or deletion of surplus lines.
