WEBrick::HTTPServer
|
Defined in: | lib/webrick/httpproxy.rb |
Overview
An HTTP Proxy server which proxies GET, HEAD and POST requests.
To create a simple proxy server:
require 'webrick'
require 'webrick/httpproxy'
proxy = WEBrick::HTTPProxyServer.new Port: 8000
trap 'INT' do proxy.shutdown end
trap 'TERM' do proxy.shutdown end
proxy.start
See .new for proxy-specific configuration items.
Modifying proxied responses
To modify content the proxy server returns use the :ProxyContentHandler
option:
handler = proc do |req, res|
if res['content-type'] == 'text/plain' then
res.body << "\nThis content was proxied!\n"
end
end
proxy =
WEBrick::HTTPProxyServer.new Port: 8000, ProxyContentHandler: handler
