Matching on Host

Use the :host request matcher to match requests on the request host.

You can use this (alone, or in combination with :path) as an alternative to :uri so that non-deterministic portions of the URI are not considered as part of the request matching.

Background ()

Given a previously recorded cassette file "cassettes/example.yml" with:

--- 
http_interactions: 
- request: 
    method: post
    uri: http://host1.com/some/long/path
    body: 
      encoding: UTF-8
      string: ""
    headers: {}
  response: 
    status: 
      code: 200
      message: OK
    headers: 
      Content-Length: 
      - "14"
    body: 
      encoding: UTF-8
      string: host1 response
    http_version: "1.1"
  recorded_at: Tue, 01 Nov 2011 04:58:44 GMT
- request: 
    method: post
    uri: http://host2.com/some/other/long/path
    body: 
      encoding: UTF-8
      string: ""
    headers: {}
  response: 
    status: 
      code: 200
      message: OK
    headers: 
      Content-Length: 
      - "16"
    body: 
      encoding: UTF-8
      string: host2 response
    http_version: "1.1"

recorded_with: VCR 2.0.0

Replay interaction that matches the host

And a file named "host_matching.rb" with:

include_http_adapter_for("<http_lib>")

require 'vcr'

VCR.configure do |c|
  <configuration>
  c.cassette_library_dir = 'cassettes'
end

VCR.use_cassette('example', :match_requests_on => [:host]) do
  puts "Response for host2: " + response_body_for(:get, "http://host2.com/home")
end

VCR.use_cassette('example', :match_requests_on => [:host]) do
  puts "Response for host1: " + response_body_for(:get,  "http://host1.com/about")
end

When I run ruby host_matching.rb

Then it should pass with:

Response for host2: host2 response
Response for host1: host1 response
