Serving ArchivesSpace user-facing applications over HTTPS

This document describes the approach for those wishing to install ArchivesSpace in such a manner that all end-user requests (i.e., URLs) are served over HTTPS rather than HTTP. For the purposes of this documentation, the URLs for the staff and public interfaces will be:

  • https://staff.myarchive.org - staff interface
  • https://public.myarchive.org - public interface

The configuration described in this document is one possible approach, and to keep things simple the following are assumed:

  • ArchivesSpace is running on a single Linux server
  • The server is running Apache or Nginx
  • You have obtained an SSL certificate and key from an authority
  • You have ensured that appropriate firewall ports have been opened (80 and 443).
  1. Configuring the Web Server
  2. Configuring ArchivesSpace

Step 1: Configure Web Server (Apache or Nginx)

Apache

Information about configuring Apache for SSL can be found at http://httpd.apache.org/docs/current/ssl/ssl_howto.html. You should read that documentation before attempting to configure SSL.

Setting up SSL

Use the NameVirtualHost and VirtualHost directives to proxy requests to the actual application urls. This requires the use of the mod_proxy module in Apache.

 NameVirtualHost *:443

 <VirtualHost *:443>
   ServerName staff.myarchive.org
   SSLEngine On
   SSLCertificateFile "/path/to/your/cert.crt"
   SSLCertificateKeyFile "/path/to/your/key.key"
   RequestHeader set X-Forwarded-Proto "https"
   ProxyPreserveHost On
   ProxyPass / http://localhost:8080/
   ProxyPassReverse / http://localhost:8080/
 </VirtualHost>

 <VirtualHost *:443>
   ServerName public.myarchive.org
   SSLEngine On
   SSLCertificateFile "/path/to/your/cert.crt"
   SSLCertificateKeyFile "/path/to/your/key.key"
   RequestHeader set X-Forwarded-Proto "https"
   ProxyPreserveHost On
   ProxyPass / http://localhost:8081/
   ProxyPassReverse / http://localhost:8081/
 </VirtualHost>

You may optionally set the Set-Cookie: Secure attribute by adding Header edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure. When a cookie has the Secure attribute, the user agent will include the cookie in an HTTP request only if the request is transmitted over a secure channel.

Setting up Redirects

When running a site over HTTPS, it's a good idea to set up a redirect to ensure any outdated HTTP requests are routed to the correct URL. This can be done through Apache as follows:

<VirtualHost *:80>
ServerName staff.myarchive.org
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://staff.myarchive.org$1 [R,L]
</VirtualHost>

<VirtualHost *:80>
ServerName public.myarchive.org
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://public.myarchive.org$1 [R,L]
</VirtualHost>

Nginx

FIXME Need nginx documentation

Step 2: Configure ArchivesSpace

The following lines need to be altered in the config.rb file:

AppConfig[:frontend_proxy_url] = "https://staff.myarchive.org"
AppConfig[:public_proxy_url] = "https://public.myarchive.org"

These lines don't need to be altered and should remain with their default values. E.g.:

AppConfig[:frontend_url] = "http://localhost:8080"
AppConfig[:public_url] = "http://localhost:8081"
AppConfig[:frontend_proxy_prefix] = proc { "#{URI(AppConfig[:frontend_proxy_url]).path}/".gsub(%r{/+$}, "/") }
AppConfig[:public_proxy_prefix] = proc { "#{URI(AppConfig[:public_proxy_url]).path}/".gsub(%r{/+$}, "/") }
