I have been reading about asp.net 2.0's client callbacks using the
ICallbackEventHandler interface.

I have also read that it is pretty much a light-weight AJAX type methodology
and that it uses the XmlHttp. Now, my understanding is not all browsers
support XmlHttp.

Can someone please let me know whether client callbacks will work in all
browsers or only specific browswers and if so, which browsers currently
support it?

Thanks

you are correct it will only work in browser with javascript enabled and
XMLHttpRequest (or the active/x control xmlhttprequest in ie before v7).
only later html 4.0 browser support it (firefox, ie, safari).

there is no fallback if javacript is disabled (although no autopostback
controls will work either such as linkbuttons).
