Is there an HTTP server which can serve files being written/appended to by some other process? I tried to serve a FIFO file with Apache but such files has zero size so Apache serves empty file even if the FIFO has some data in it.
This has a helpful example: http://linuxgazette.net/123/smith.html
Uses php to parse the fifo and shunts it to browser... then ajax to refresh
If you are wanting to have several/many users accessing, you will need some form of fanout, like his previous page.. handy!
