= AddHttpHeader

This gem provides Rack middleware which adds an http header to the response. You can either add a hard coded header, or provide a block that will get evaluated at runtime.

== Example

Add the host and build version to the header to make debugging production issues easier

host_info = "#{hostname.split('.').first}; #{BUILD_VERSION}" Rails.configuration.middleware.insert_before(0, AddHttpHeader, 'X-Host-Info' => host_info)

Add debug info about the request only on errors

Rails.configuration.middleware.insert_before(0, AddHttpHeader, 'X-Debug' => lambda{|env, status, headers| DebugInfo(env) if status >= 500})
