in reply to OO CGI Engine
I would like to second the suggestion that you move away from CGI and get mod_perl installed on your machine. What I have had a great deal of luck using under mod_perl is HTML::Embperl by Gerald Richter. The free tech support he offers on his site is excellent.
Also, there is another module by GR called DBI::Recordset that encapsulates database IO in object methods. I must admit that I don't use it, but I have heard good feedback about it.
General advice on the topic of rolling your own OO CGI engine is that it probably makes more sense to conduct more research into existing modules before taking on the task of building your own. I am not saying that there is no justification for building your own, just that I can't envision doing this myself. I am too lazy and I like chicken.
