If you are not comfortable with
AJAX, here is an alternative. The idea is you use
IE inter page transitions. Put these tags in the head of your html document.
<META http-equiv="Page-Enter" content="blendTrans(Duration=0.2)">
<META http-equiv="Page-Exit" content="blendTrans(Duration=0.2)">
Essentially what IE does is capture an image of the page before, and then
Renders the new page in memory first to create a second image. It then uses DirectX to smoothly
Blend one image to another.
This simple trick alone gives you about 50% of the benefit of
ajax,with a 1% of the effort.
To get the full benefits of ajax,you will of course need to use
