The lastModified date is not always defined, I haven't checked for a while but in many cases the server sends wrong or undefined dates. So it is not only a question of making a "touch" on the file, but dealing with specific cases in the code path. That makes it less useful, unfortunately. Do you have data on the frequency of wrong and right dates on the Web? Example: NY Times for the article [1] created on 6 October 2010 returns the following information: * Date: Wed, 09 Nov 2011 02:38:53 GMT * Expires: Thu, 01 Dec 1994 16:00:00 GMT and no Last-Modified: header, which will trigger different type of answers for the lastModified DOM (depending on the browser.)
