I am more excited about ETags support than SPDY & Websockets. Etags (when used correctly) are extremely handy.

    There's a great example/explanation on the Facebook Developer blog: https://developers.facebook.com/blog/post/627/ https://developers.facebook.com/blog/post/627/ Basically, it's Last-Modified on steroids.

      In the link that you mentioned, ETags are produced and handled by application. There are no special needs in web-server support.

        Right... I was assuming that the OP wanted to know what ETags are, rather than their specific implementation in nginx.

          Etags are useful for static assets as well.
