My career falls into the following progressive stages. Geographical load balancing of images. Virtual images which allow us to return the best possible image for a particular browser. Fine granularity content negotiation allowing us to return html 2.0 and html 3.0 attributes depending on browser type. The translation from 2.0 to 3.0 is done automatically by software conversion in the server.
Server side includes that can be cached on a per file basis.
I have been using mod-perl and Apache to duplicate many of these features. Unfortunately, the server still has some very interesting web marketing features that I havn't ported yet so we are using this server for some pages. A Southern Golf and Vacation Guide and have been actively building Relocation Central since 1998. This site is created using spider technology that helps create the pages and keep links up to date. If you have similiar interests, drop me a line and we might be able to work together and create a wonderful kids site.
