[jQuery] IE ajax request giving the same result every time it's called


Hi,
Every ten seconds I'm checking the id of the last entry in my
database. For this purpose I'm using a GET ajax request calling a
really simple PHP code.
This step works wonderfully for Firefox and Safari on PCs and Macs. IE
however seems to return the same number over and over (the number it
got from its first request), although I'm positive that the db has
been updated correctly.
Anyone familiar with this random behavior from IE?
Clem.
