Question on AJAX enabling a website

I have a question for those of you who have AJAX enabled your website. My company hired a consulting company to re-write our ASP site into NET. When the project leader from the consulting company was demonstrating the site's functionality to our company, I asked a few questions. I was particularly concerned that a number of pages were doing excessive page postbacks. When I asked whether these pages could implemented with an AJAX control like an Update Panel, he recommended using AJAX only when necessary. His reason was that the product isn't mature yet and that a number of browsers are having computability problems with Javascript being rendered. Not that we have any non-USA clients,, but he claims that this particularly true non-USA browsers. Has anyone else found this to be true?

Thanks

but he claims that this particularly true non-USA browsers.

Maybe we should define what are those "non-USA browsers" are...

Thanks for your response. Perhaps "non-USA" browsers was a poor term on my part. Essentially I was told that some of their foreign users were having trouble using AJAX sites from their sites. I was just wondering whether anyone encountered browser incompatability with AJAX or the AJAX Component Toolkit.

In short : No, he's feeding you a line. I've personally had some pretty good success w/ AJAX as a principle. I've not investigated Microsoft's AJAX library intensively but it also looks like it's pretty well written.

He's trying to FUD you out of making him better design the application. The ASP.NET AJAX framework is as robust as any you'll find. No reason at all to avoid it.
