You know the drill. In your Gemfile, have the line
```ruby
gem 'rails-reverse-proxy'
```
Then (you guessed it!)
```
$ bundle
```
## Usage
An example usage of this gem is hosting a WordPress site on a path within your Rails application, such as `/blog`. To do this, you'll need something like
```ruby
class WordpressController <ApplicationController
include ReverseProxy::Controller
def index
# Assuming the WordPress server is being hosted on port 8080
reverse_proxy "http://localhost:8080" do |config|
# We got a 404!
config.on_missing do |code, response|
redirect_to root_url and return
end
# There's also other callbacks:
# - on_set_cookies
# - on_response
# - on_set_cookies
# - on_success
# - on_redirect
# - on_missing
# - on_error
# - on_complete
end
end
end
```
Then in your `routes.rb` file, you should have something like
```ruby
match 'blog/*path' => 'wordpress#index', via: [:get, :post, :put, :patch, :delete]
