(Second try. I think I replied once already, but perhaps forgot to press the final "submit". Here's that reply once again...) I used HTTPi a year ago or so. It's written in pure Perl, it's tiny and requires no Perl modules. It can be configured to run Perl CGI scripts directly, re-using the interpreter instance (less overhead). When I used HTTPi, it was for launching actions (CGI scripts) from web browser bookmarklets to do things like Youtube video download, direct play using mplayer... Nowadays there are better solutions for that, so I forgot all about it. There's also Perl Web Server, but it seems to require Perl modules that are not present on OS 2008 by default.
