1.47 raeburn 3129: #
3130: # The Apache SSL configuration used by LON-CAPA is contained in
3131: # two files: sslrewrite.conf and loncapassl.conf.
3132: #
3133: # Starting with LON-CAPA 2.12, name-based virtual hosts are used
3134: # with port 443. The default virtual host (i.e., the one listed
3135: # first) is for the server's standard hostname, and that is the one
3136: # which will respond to client browser requests for https:// pages.
3137: #
3138: # Accordingly, a system administrator will need to edit the config
3139: # config file to include paths to a signed SSL certificate (public),
3140: # chain (public) and key (private) pem files. The certificate should
3141: # have been signed by a recognized certificate authority ((e.g.,
3142: # InCommon or Let's Encrypt).
3143: #
3144: # The sslrewrite.conf file contains the rewrite configuration for
3145: # the default virtual host. The rewrite rules defined are used to
3146: # allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served
3147: # http://, in order to support vertical alignment of mimetex images
3148: # (one of the options for rendering Math content); (b) allow requests
3149: # for certain URLs (external resource, and syllabus, if external URL
3150: # used) to be served http:// to accommodate the use of iframes which
3151: # would otherwise result in browser blocking of mixed active content.
3152: #
3153: # The loncapassl.conf file contains the configuration for the
3154: # "internal" virtual host, which will respond to requests for https://
3155: # pages from other LON-CAPA servers in the network to which the node
3156: # belongs. The ServerName is internal-<hostname> where <hostname>
3157: # is the server's hostname. There is no need to create a DNS entry
3158: # for internal-<hostname>, as LON-CAPA 2.12 automatically performs
3159: # the required hostname to IP mapping.
3160: #
3161: # Requests to /raw on the "internal" virtual host require a valid
3162: # SSL client certificate, signed by the certificate authority
3163: # for the LON-CAPA network to which the node belongs.
3164: #
3165: # The configuration file to which the contents of sslrewrite.conf
3166: # and loncapassl.conf will be written will have either been identified
3167: # when &chkapachessl() was run, or if no files were found with
3168: # existing rewrite blocks, then a candidate file will be chosen
3169: # from the .conf files containing VirtualHosts definitions.
3170: # If there is more than one suitable candidate file, the system
3171: # administrator will be prompted to select from the available files.
3172: #
3173: # If there are no files containing VirtualHosts definitions, then
3174: # <VirtualHost *:443> </VirtualHost> blocks will be appended to
3175: # the standard Apache SSL config for the particular distro:
3176: # ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf
3177: # for SuSE/SLES, and default-ssl.conf for Ubuntu.
3178: #
3179: # Once a file is selected, the contents of sslrewrite.conf and
3180: # loncapassl.conf are compared with appropriate blocks in the file
3181: # and the user will be prompted to agree to insertion of missing lines
3182: # and/or deletion of surplus lines.
