But don't forget that there are other technologies other than servlets that cache code so that they don't need to be recompiled for each hit. ...And this being a Perl list there is mod_perl a plugin for Apache (free) and PerlEx for IIS (from ActiveState).

A Servlet is instantiated for the first request and any subsequent requests to the same servlet spawns a separate thread, whereas CGIs are costly and had to be instantiated afresh for every fresh request. This way CGIs are more prone to bottlenecks and timeouts than Servlets. -- Rex > -----Original Message----- > From: Brett W.
