add HTTP response headers
hi, is it possible to add static and dynamic HTTP response headers in unicorn.conf.rb? i'd like to add the hostname of the worker for debugging and a timestamp, when the request was worked on. currently this is done in nginx, which should be stripped from the stack. i'd like to keep it out of the webapp itself, because it's infrastructure. cheers pille ___ Unicorn mailing list - mongrel-unicorn@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying

Can you consider config.ru infrastructure? unicorn tries to do as much generically via Rack as possible. The following (totally untested) middleware should work: 8 require 'time' require 'socket' require 'rack/utils' # Usage (in config.ru) # require 'name/of/this/file' # use ExtraHeaders # # other middlewares ... # run YourApp.new class ExtraHeaders def initialize(app) @app = app end def call(env) start = Time.now.httpdate status, headers, body = @app.call(env) headers = Rack::Utils::HeaderHash.new(headers) headers[X-Hostname] = Socket.gethostname headers[X-Start] = start [ status, headers, body ] end end 8 ___ Unicorn mailing list - mongrel-unicorn@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
