I prefer using the XHTML mime type for pages, instead of HTML, and serve a different mime type to IE, but when I do this, should I use XML DOM or HTML DOM?
Do you mean DOCTYPE or do you really mean mime type? And, why do you prefer sending html to IE and xhtml to everyone else? Seems like an unnecessary complication.
As a side note, why would anyone whose audience is the general public prefer serving XHTML over HTML? I should probably ask that in another thread if I really want an answer...
