In 1994 I was in high school, and there were no animated GIFs. One way you could make images move in the web browser was to use a mechanism similar to this.<p>I wrote a C program which would load 6 frames of a smiley face animation and would feed them sequentially, in an endless loop, to anyone who requested the image. Mosaic was happy to animate them.<p>I get called in to the web mistress's office. The web server is down. We had a donated Silicon Graphics Origin server, if my memory serves me correctly. This was a beefy machine.<p>The cgi-bin C program would load 6 images, as fast as it possibly could, and dump them into a network socket. It would not throttle. It would not check if the client disconnected. It had one job. It did it efficiently, and ruthlessly.<p>Poor server.
