1.47 raeburn 2649: #
2650: # The Apache SSL configuration used by LON-CAPA is contained in
2651: # two files: sslrewrite.conf and loncapassl.conf.
2652: #
2653: # Starting with LON-CAPA 2.12, name-based virtual hosts are used
2654: # with port 443. The default virtual host (i.e., the one listed
2655: # first) is for the server's standard hostname, and that is the one
2656: # which will respond to client browser requests for https:// pages.
2657: #
2658: # Accordingly, a system administrator will need to edit the config
2659: # config file to include paths to a signed SSL certificate (public),
2660: # chain (public) and key (private) pem files. The certificate should
2661: # have been signed by a recognized certificate authority ((e.g.,
2662: # InCommon or Let's Encrypt).
2663: #
2664: # The sslrewrite.conf file contains the rewrite configuration for
2665: # the default virtual host. The rewrite rules defined are used to
2666: # allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served
2667: # http://, in order to support vertical alignment of mimetex images
2668: # (one of the options for rendering Math content); (b) allow requests
2669: # for certain URLs (external resource, and syllabus, if external URL
2670: # used) to be served http:// to accommodate the use of iframes which
2671: # would otherwise result in browser blocking of mixed active content.
2672: #
2673: # The loncapassl.conf file contains the configuration for the
2674: # "internal" virtual host, which will respond to requests for https://
2675: # pages from other LON-CAPA servers in the network to which the node
2676: # belongs. The ServerName is internal-<hostname> where <hostname>
2677: # is the server's hostname. There is no need to create a DNS entry
2678: # for internal-<hostname>, as LON-CAPA 2.12 automatically performs
2679: # the required hostname to IP mapping.
2680: #
2681: # Requests to /raw on the "internal" virtual host require a valid
2682: # SSL client certificate, signed by the certificate authority
2683: # for the LON-CAPA network to which the node belongs.
2684: #
2685: # The configuration file to which the contents of sslrewrite.conf
2686: # and loncapassl.conf will be written will have either been identified
2687: # when &chkapachessl() was run, or if no files were found with
2688: # existing rewrite blocks, then a candidate file will be chosen
2689: # from the .conf files containing VirtualHosts definitions.
2690: # If there is more than one suitable candidate file, the system
2691: # administrator will be prompted to select from the available files.
2692: #
2693: # If there are no files containing VirtualHosts definitions, then
2694: # <VirtualHost *:443> </VirtualHost> blocks will be appended to
2695: # the standard Apache SSL config for the particular distro:
2696: # ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf
2697: # for SuSE/SLES, and default-ssl.conf for Ubuntu.
2698: #
2699: # Once a file is selected, the contents of sslrewrite.conf and
2700: # loncapassl.conf are compared with appropriate blocks in the file
