But even more important it also uses client side caching.</p> <blockquote> <p>If the app's get method returns JSON, what is the correct method to handle compress result? should I first check the http.request header's "accept-encoding" and make sure it support gzip, then compress the JSON result? or gzippo will automatically handle it?</p> </blockquote> <p>I think you stand correct. I don't believe Gzippo will handle other routes, but only static folder.</p> <hr> <p>Some other tips:</p> <ul> <li>You should combine all your js/css when deploying => <a href="http://developer.yahoo.com/performance/rules.html#num_http" rel="nofollow">http://developer.yahoo.com/performance/rules.html#num_http</a>.
