This is more like a streaming data server, which is a very different beast from a webserver, and probably better suited to the job. Usually either multithreaded or single-process using select() (just like Squid). You could probably build one pretty easily. Using a 30MB Apache process to serve one client for half an hour seems like a hell of a waste of RAM. > A squid proxy would probably cause severe problems when > dealing with a > script that does not complete output for a variable rate of time. No, it's fine, squid gives it to the client as it gets it, but can receive from the server faster.
