How about:
class GzipOutputFilter
def initialize(app)
@app = app
end
def call(env)
out = @app.call(env)
gzip = IO.popen('gzip', 'r+')
gzip.write out[2] # handles String only, would be nice to check
for IO object too
gzip.close_write
out[1]['Content-encoding'] = 'gzip'
out[2] = gzip
out
end
end
class HelloHandler
def call(env)
[ 200, { 'Content-type' => 'text/plain' }, 'hello, world' ]
end
end
use Rack::Lint
use GzipOutputFilter
run HelloHandler.new
