LispForum

I'm very late to post, so this is probably all over, but I've seen the "Premature end of script headers" error before programming cgi in clisp, usually because there's a problem somewhere in the #! line (wrong path to lisp, wrong init options, or any other error). Hope this helps...

Additionally, I've often managed to speed up code by about 2 to 3 times (if I'm lucky) by compiling the clisp function. If you run your code interpreted, there's a performance hit, but I'm not sure how much these days (clisp has a JIT, the last I hear).
