Not sure if this is common knowledge or not, but, when developing under FF, I was using a relative URL to perform ajax loads:
<pre> $('container').load('images?pidx=1'); </pre> When I moved to IE8, found that this didn't work and had to use an absolute: <pre> $('container').load('/context/images?pidx=1'); </pre> Hope that helps someone. .:|S|:.
