Why not serve both compressed and uncompressed versions?

Amen to that! Say, Greg, how's about posting the URL of your Blacktron Galaxy
Explorer over in the .build group? Probably a lot of new-timers there who
haven't seen it yet.

Not a problem. I'd probably nix the CGI on something like that, though, and
serve static .dat files for parts. (Apache can to be told to serve static
.dat files as application/x-ldraw just as easily as CGI scripts can send DAT
content that way, but CGI scripts incur the additional overhead of starting up
a command interpreter).
Another option would be to run a separate HTTP daemon dedicated to serving
parts on a different port (URLs would look like <http://www.lugnet.com:x/y>
where x and y would be the port and part numbers, respectively). This would
be easy to set up and would be extremely fast, but would probably still offer
no particular gain over Apache because commonly used parts would already be in
the OS filesystem cache if Apache was serving them.

Yeah, it could all be done without much trouble. Apache can very easily be
configured to serve anything as anything and it's wicked fast and there's lots
of disk space and bandwidth available. Compression would really be nice for
speeding delivery, especially if we're talking 4x to 10x.

| (...) Isn't there something you can do to have just *one* perl interpreter running, that does all the CGIing, instead of starting up all these processes? Jasper "can't imagine at what PID that server is by now" Janssen (26 years ago, 27-Feb-99, to lugnet.cad.dev, lugnet.cad)
