   on a related topic,

   apache uses later_than() (util.c)  to decide if a document has changed.

   The algorithm there looks time consuming. 
   Can't this be done with a string comparision ?

Even if the answer is, in general, no, doing a string comparison as an
initial quick check might be a useful optimization.
