REVERSE PROXY PLUGIN Version 1.1 (May 3rd, 2009)
Copyright 2006-2009 Brian Hogan
This plugin is designed to allow your Rails application to reside behind a reverse proxy. When the plugin is configured and the application is running in production mode, any URLs generated by Rails helpers will automatically be prefixed with the host and path you specify.
An organization may be interested in running a Rails application behind a reverse proxy such as Apache. However, any URLs generated by the Rails appliction would expose the proxy.
The plugin would be configured to prepend www.mydomain.com/app1 to all URLs generated by the application.
Usage and Configuration
The official version can be installed via Subversion using the Ruby script/plugin install command. In the root of your Rails application structure (where you can see the app/ vendor/ and public/ folders) execute the following command:
ruby script/plugin install http://svn.napcsweb.com/public/reverse_proxy_fix
The code is also available on Github and can be installed via
ruby script/plugin install firstname.lastname@example.org:napcs/reverse_proxy_fix.git
The version on Github will always be the most recent version. However, we'll always use tags for releases, so when you check it out, you may want to switch to a specific tag. The Subversion site will always contain the most recent stable version of the plugin, so if you just want things to work out of the box, you should consider using that instead.
You will be prompted by the script to specify the version of Rails you're using. Select the version that best matches your version of Rails and press the Enter key.
For Rails pre-2.3, you will be prompted to enter the base url of your front-end server when you install the plugin via script/plugin install.
For Rails 2.3+, you will need to add BASE_URL somewhere in your environment configuration, for example in config/development.rb
You should not include the trailing slash! For example:
If that doesn't work for some reason, you can run the install.rb script in
Or you can manually edit the file lib/config.rb and uncomment the BASE_URL line. (It should be the only line in the file. Enter the desired base url that you would like the plugin to prepend to any generated URLs.
Running In Production
Rails pre-2.3, this plugin only operates in production mode. Otherwise, in Rails 2.3+, it runs whenever BASE_URL is defined.
Versions of Rails
This plugin supports Rails 1.x, Rails 1.2.x, and Rails 2.0 by using separate files for each Rails version During the installation you'll need to tell the plugin which version to use. If this fails for some reason, simply rename the appropriate file to reverse_proxy_fix.rb
* 116.rb (Rails 1.1.6 or below) * 123.rb (Rails 1.2.X) * 20.rb (Rails 2.0-2.2) * 23.rb (Rails 2.3.x)
Then start your application in Production mode. The plugin is automatically disabled when you run in development mode, so you don't need to do any special configurations to develop your application.
First, asset hosts are disabled and overruled by this plugin. Your asset host base URL is set to the base url you specify. Modify the plugin to change this behavior. I am open to patches for this, and am also looking at better solutions.
Second, in order to get named routes working in Rails 2.0 I took the shortcut and disabled route optimization. This is suboptimal, and am looking for patches from users.
* Added specs for Rails 2.3+ * Rails 2.3+ now only need to define BASE_URL in any environment for the plugin to be enabled * Refactored to use alias_method_chain instead of alias, reset_asset_host_and_route_optimization to its own method * Fixed request.path, request.url (which will fix cache keys etc.) * Updated readme, installation
* Added support for Rails 2.3
* Updated install script to specify that this does in fact work with Rails 2.1 and 2.2.
* Updated the readme version and fixed the installation script so it worked for platforms other than Windows (Thanks to Brian Candler for catching this and supplying a patch)
* Fixed the issue that prevented named routes from not working in Rails 2.0 by disabling named route optimization.
* Fixed the installer script to properly select Rails version. (Joshua Miller)
* Added support for Rails 2.0 - needs more testing
* Unified installer for all Rails versions again.
* Fixed an issue when using RESTful routing - plugin should no longer activate in dev mode.
* Added a rake task to configure the plugin * fixed a situation where the installer didn't work in Rails 1.2.3 * fixed a problem with request.request_uri not setting the base path. * Overloaded routing mechanism to avoid collisions with the modified request.request_uri * Tested with acts_as_authenticated
* Fixed issue where page caching does not work. The URL rewriting can now be turned off by sending *:skip_relative_url_root => true* to any calls to url_for or link_to. (This is the method that caching uses to build the cached urls)
* Small bug fix to allow :only_path => false to work correctly when called on link_to and url_for
* Initial Release
