Certainly not.  HTML is not Turing-complete.  In fact, detecting and
preventing infinite loops and recursion in HTML simply requires
traversing a directed acyclic graph and determining that it is, in
fact, acyclic.  This is simple.

Perhaps you're thinking of DHTML.  Or perhaps you're thinking of some
kind of evil, twisted web server that serves up the same page under an
infinite number of different names, each modified to include a frame
reference to that page under a different name.
