according to this post:

It seems that the problem is caused by the way browsers render pages differently when the doctype is not specified.

Here is another interesting post i found on this subject, still not the solution though:

on the above page it has "Response.Cache.SetNoStore()" as a possible solution in the comments, i'll try this next to see if it helps.
