Here’s something of interest. I’ve been using lots of Ajax software recently – like Meebo.com and ThinkFree . It would be good to read this post below if you are a Ajax developer.
If you have developed an AJAX based web application you would know how many JavaScript files are required per webpage. If you use the prototype or dojo toolkit library you would know how big those JavaScript files can turn out to be.
A few months back I was developing a website dotbeta.com, though I never completed it, I learned a few things about caching and how you can speed up your website for users who visit your site often. A website like digg takes up more than a minute to load on my dialup connection even though the main page is no more than a 27-32 KB. The real time is taken up by the JavaScript files. The solution for this problem is to cache the JavaScript files. Though caching improves the speed but it causes a problem when you have to update the JavaScript files, since the browser will not look for updated files if they have been cached.
