With the roll-out of NS6, IFRAMES will rapidly overtake LAYERS and ILAYERS for handling some cross-browser coding, but we may have a legacy issue with NS4 browsers for some time to come. Does anyone have the js code for sniffing NS4 only, with everything else being the default?
I'm going to inject banner rotation using ILAYERS into pages being served to NS4, everything else gets an IFRAME. I'm currently testing for every browser under the sun and no longer see the need. I could drop 20k or more of js by just testing for NS4.
