Here is an interesting thread in ESRI forum about ArcGIS Server support on Google Chrome. Since google chrome is released, am wondering how does ESRI going to fit into new shoes. Surprisingly this post from ESRI came with an example and shows the template is not fitting. Though chrome released much later than 9.3 we hope ESRI or some professionals will provide some clues to make it fit in new browser.
