in reply to how to improve my script

From looking at your code, it appears that it is vulnerable to directory traversal attacks. If someone requests URLs like "/../../../../../../etc/passwd", you happily deliver the system's user database.

Also I'd guess that you'll get a lot of warnings if a client terminates the connection without sending a request.

However I may be wrong; I did not run your code, I only had a look at it.

I realize that you are doing this only as an exercise, but I'd strongly recommend thinking about malicious input when writing networking software.

I'm missing taint mode and any kind of input validation. I see code written in Perl4 style (&log(...)), I see repeated (hidden) stat calls (-e $DOCROOT.$uri, then -d $DOCROOT.$uri, then -f $DOCROOT.$uri), I see open where stat is sufficient (# open $f to get its modification time). And I'm sure perlcritic would find a lot more than this.
