2905: # The Apache SSL configuration used by LON-CAPA is contained in
2906: # two files: sslrewrite.conf and loncapassl.conf.
2907: #
2908: # Starting with LON-CAPA 2.12, name-based virtual hosts are used
2909: # with port 443. The default virtual host (i.e., the one listed
2910: # first) is for the server's standard hostname, and that is the one
2911: # which will respond to client browser requests for https:// pages.
2912: #
2913: # Accordingly, a system administrator will need to edit the config
2914: # config file to include paths to a signed SSL certificate (public),
2915: # chain (public) and key (private) pem files. The certificate should
2916: # have been signed by a recognized certificate authority ((e.g.,
2917: # InCommon or Let's Encrypt).
2918: #
2919: # The sslrewrite.conf file contains the rewrite configuration for
2920: # the default virtual host. The rewrite rules defined are used to
2921: # allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served
2922: # http://, in order to support vertical alignment of mimetex images
2923: # (one of the options for rendering Math content); (b) allow requests
2924: # for certain URLs (external resource, and syllabus, if external URL
2925: # used) to be served http:// to accommodate the use of iframes which
2926: # would otherwise result in browser blocking of mixed active content.
2927: #
2928: # The loncapassl.conf file contains the configuration for the
2929: # "internal" virtual host, which will respond to requests for https://
2930: # pages from other LON-CAPA servers in the network to which the node
2931: # belongs. The ServerName is internal-<hostname> where <hostname>
2932: # is the server's hostname. There is no need to create a DNS entry
2933: # for internal-<hostname>, as LON-CAPA 2.12 automatically performs
2934: # the required hostname to IP mapping.
2935: #
2936: # Requests to /raw on the "internal" virtual host require a valid
2937: # SSL client certificate, signed by the certificate authority
2938: # for the LON-CAPA network to which the node belongs.
2939: #
2940: # The configuration file to which the contents of sslrewrite.conf
2941: # and loncapassl.conf will be written will have either been identified
2942: # when &chkapachessl() was run, or if no files were found with
2943: # existing rewrite blocks, then a candidate file will be chosen
2944: # from the .conf files containing VirtualHosts definitions.
2945: # If there is more than one suitable candidate file, the system
2946: # administrator will be prompted to select from the available files.
2947: #
2948: # If there are no files containing VirtualHosts definitions, then
2949: # <VirtualHost *:443> </VirtualHost> blocks will be appended to
2950: # the standard Apache SSL config for the particular distro:
2951: # ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf
2952: # for SuSE/SLES, and default-ssl.conf for Ubuntu.
2953: #
2954: # Once a file is selected, the contents of sslrewrite.conf and
2955: # loncapassl.conf are compared with appropriate blocks in the file
2956: # and the user will be prompted to agree to insertion of missing lines
2957: # and/or deletion of surplus lines.
