I think you are confusing an animated gif with a server push animation.
An animated gif89a is a single file with multiple images which is
interpreted locally by the browser. It is a single file in your server logs.
With a server push animation it is, believe it or not, still a single hit to
the server. The beauty (and curse) of server push is that the connection is
maintained for the duration of the transmission. The MIME type is
multipart/mixed (I believe...) and that means that the browser must maintain
a connection to the server, instead of dropping the connection. Etiher way
there is a single connection in both instances. The gif89a causes less
strain on the server. I refuse to comment on what I believe they do to the
