3060: # The Apache SSL configuration used by LON-CAPA is contained in
3061: # two files: sslrewrite.conf and loncapassl.conf.
3062: #
3063: # Starting with LON-CAPA 2.12, name-based virtual hosts are used
3064: # with port 443. The default virtual host (i.e., the one listed
3065: # first) is for the server's standard hostname, and that is the one
3066: # which will respond to client browser requests for https:// pages.
3067: #
3068: # Accordingly, a system administrator will need to edit the config
3069: # config file to include paths to a signed SSL certificate (public),
3070: # chain (public) and key (private) pem files. The certificate should
3071: # have been signed by a recognized certificate authority ((e.g.,
3072: # InCommon or Let's Encrypt).
3073: #
3074: # The sslrewrite.conf file contains the rewrite configuration for
3075: # the default virtual host. The rewrite rules defined are used to
3076: # allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served
3077: # http://, in order to support vertical alignment of mimetex images
3078: # (one of the options for rendering Math content); (b) allow requests
3079: # for certain URLs (external resource, and syllabus, if external URL
3080: # used) to be served http:// to accommodate the use of iframes which
3081: # would otherwise result in browser blocking of mixed active content.
3082: #
3083: # The loncapassl.conf file contains the configuration for the
3084: # "internal" virtual host, which will respond to requests for https://
3085: # pages from other LON-CAPA servers in the network to which the node
3086: # belongs. The ServerName is internal-<hostname> where <hostname>
3087: # is the server's hostname. There is no need to create a DNS entry
3088: # for internal-<hostname>, as LON-CAPA 2.12 automatically performs
3089: # the required hostname to IP mapping.
3090: #
3091: # Requests to /raw on the "internal" virtual host require a valid
