The website technology supporting Philadelphia Reflections is PHP, MySQL and DHTML. The web hosting service is Internet Planners. The development of this website has provided an opportunity to learn new technology, to try out different techniques for getting noticed by the search engines and the trials and tribulations of dealing with malicious hackers and spammers who range from the annoying to the abusive. This collection of articles documents some of our experiences and we hope that people surfing the web looking for solutions to problems we've encountered will benefit.

Compression can reduce the size of the text (not images) of your web pages as they are transmitted outbound to the client. This will have only a small impact on response time over modern fiber connections but it will significantly reduce your bandwidth consumption (70% on average on this site.)
In XHTML vs. HTML I show how I implemented gzip compression on this site. The problem with that method is that it's a pain. Soon another website, I tried out the Apache access method to instruct the server to compress all outbound pages. Works like a charm.
