As web developers, we have a serious issue to contend with: completely all-over-the-place support for Ajax. Prototype does a great job of abstracting the various browsers, but there are several pitfalls coming our way. XMLHttpRef is implemented as an ActiveX control inside IE, and that means that if a user has IE set to High Security mode, it’s not going to work – even though it’s an internal component! Further, the new changes Microsoft is being forced to implement as a result of a lawsuit ruling would see IE users having to click a response each time ActiveX is used in the browser. It’s unclear how this might impact how we use Ajax in our web applications.
