MSIE's take on If-Modified-Since

IE supplies a length parameter to the If-Modified-Since header, causing
perlbal to incorrectly return the full content.  Like so:

  If-Modified-Since: Fri, 30 Dec 2005 19:03:59 GMT; length=1406

Perlbal compares the header value directly against a date string and
great waves of excessive transfer ensue.
