988: # for SuSE/SLES, and default-ssl.conf for Ubuntu.

990: # Once a file is selected, the contents of sslrewrite.conf and

2392: # The Apache SSL configuration used by LON-CAPA is contained in
2393: # two files: sslrewrite.conf and loncapassl.conf.
2394: #
2395: # Starting with LON-CAPA 2.12, name-based virtual hosts are used
2396: # with port 443. The default virtual host (i.e., the one listed
2397: # first) is for the server's standard hostname, and that is the one
2398: # which will respond to client browser requests for https:// pages.
2399: #
2400: # Accordingly, a system administrator will need to edit the config
2401: # config file to include paths to a signed SSL certificate (public),
2402: # chain (public) and key (private) pem files. The certificate should
2403: # have been signed by a recognized certificate authority ((e.g.,
2404: # InCommon or Let's Encrypt).
2405: #
2406: # The sslrewrite.conf file contains the rewrite configuration for
2407: # the default virtual host. The rewrite rules defined are used to
2408: # allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served
2409: # http://, in order to support vertical alignment of mimetex images
2410: # (one of the options for rendering Math content); (b) allow requests
2411: # for certain URLs (external resource, and syllabus, if external URL
2412: # used) to be served http:// to accommodate the use of iframes which
2413: # would otherwise result in browser blocking of mixed active content.
2414: #
2415: # The loncapassl.conf file contains the configuration for the
2416: # "internal" virtual host, which will respond to requests for https://
2417: # pages from other LON-CAPA servers in the network to which the node
2418: # belongs. The ServerName is internal-<hostname> where <hostname>
2419: # is the server's hostname. There is no need to create a DNS entry
2420: # for internal-<hostname>, as LON-CAPA 2.12 automatically performs
2421: # the required hostname to IP mapping.
2422: #
2423: # Requests to /raw on the "internal" virtual host require a valid
2424: # SSL client certificate, signed by the certificate authority
2425: # for the LON-CAPA network to which the node belongs.
2426: #
2427: # The configuration file to which the contents of sslrewrite.conf
2428: # and loncapassl.conf will be written will have either been identified
2429: # when &chkapachessl() was run, or if no files were found with
2430: # existing rewrite blocks, then a candidate file will be chosen
2431: # from the .conf files containing VirtualHosts definitions.
2432: # If there is more than one suitable candidate file, the system
2433: # administrator will be prompted to select from the available files.
2434: #
2435: # If there are no files containing VirtualHosts definitions, then
2436: # <VirtualHost *:443> </VirtualHost> blocks will be appended to
2437: # the standard Apache SSL config for the particular distro:
2438: # ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf
2439: # for SuSE/SLES, and default-ssl.conf for Ubuntu.
2440: #
2441: # Once a file is selected, the contents of sslrewrite.conf and
2442: # loncapassl.conf are compared with appropriate blocks in the file
2443: # and the user will be prompted to agree to insertion of missing lines
2444: # and/or deletion of surplus lines.
