Hi Taco, My 2 cents on this matter is to use IIS or Apache or whetever webserver you are using and properly set content expiration headers on everything that is static, e.g. your .css files, any images you are loading, and javascript. On our site, it's 12 hours for the images, css, and and js files.
Forget about trying to set expiration times on dynamic pages especially if there are going to be parameters in the querystring. It just won't work reliably. Instead, invest in ZipEnable or gzip or other HTTP compression software to reduce the html filesize of the content you are delivering. If instead you are trying to reduce the number of hits to a database or server load - which probably would be a concern for 95,000 request a day, you'll need to tweak the Database Caching settings of Coldfusion Administrator and/or look into a page caching tag such as CF_Accelerate. If you need to improve user waiting time, consider that the visitors upload bandwidth is most likely one the more limiting factors, and the best way to address this is to reduce the number of cookies you are setting.
