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