1.47 raeburn 3135: #
3136: # The Apache SSL configuration used by LON-CAPA is contained in
3137: # two files: sslrewrite.conf and loncapassl.conf.
3138: #
3139: # Starting with LON-CAPA 2.12, name-based virtual hosts are used
3140: # with port 443. The default virtual host (i.e., the one listed
3141: # first) is for the server's standard hostname, and that is the one
3142: # which will respond to client browser requests for https:// pages.
3143: #
3144: # Accordingly, a system administrator will need to edit the config
3145: # config file to include paths to a signed SSL certificate (public),
3146: # chain (public) and key (private) pem files. The certificate should
3147: # have been signed by a recognized certificate authority ((e.g.,
3148: # InCommon or Let's Encrypt).
3149: #
3150: # The sslrewrite.conf file contains the rewrite configuration for
3151: # the default virtual host. The rewrite rules defined are used to
3152: # allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served
3153: # http://, in order to support vertical alignment of mimetex images
3154: # (one of the options for rendering Math content); (b) allow requests
3155: # for certain URLs (external resource, and syllabus, if external URL
3156: # used) to be served http:// to accommodate the use of iframes which
3157: # would otherwise result in browser blocking of mixed active content.
3158: #
3159: # The loncapassl.conf file contains the configuration for the
3160: # "internal" virtual host, which will respond to requests for https://
3161: # pages from other LON-CAPA servers in the network to which the node
3162: # belongs. The ServerName is internal-<hostname> where <hostname>
3163: # is the server's hostname. There is no need to create a DNS entry
3164: # for internal-<hostname>, as LON-CAPA 2.12 automatically performs
3165: # the required hostname to IP mapping.
3166: #
3167: # Requests to /raw on the "internal" virtual host require a valid
3168: # SSL client certificate, signed by the certificate authority
3169: # for the LON-CAPA network to which the node belongs.
3170: #
3171: # The configuration file to which the contents of sslrewrite.conf
3172: # and loncapassl.conf will be written will have either been identified
3173: # when &chkapachessl() was run, or if no files were found with
3174: # existing rewrite blocks, then a candidate file will be chosen
3175: # from the .conf files containing VirtualHosts definitions.
3176: # If there is more than one suitable candidate file, the system
3177: # administrator will be prompted to select from the available files.
3178: #
3179: # If there are no files containing VirtualHosts definitions, then
3180: # <VirtualHost *:443> </VirtualHost> blocks will be appended to
3181: # the standard Apache SSL config for the particular distro:
3182: # ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf
3183: # for SuSE/SLES, and default-ssl.conf for Ubuntu.
3184: #
3185: # Once a file is selected, the contents of sslrewrite.conf and
3186: # loncapassl.conf are compared with appropriate blocks in the file
3187: # and the user will be prompted to agree to insertion of missing lines
3188: # and/or deletion of surplus lines.
