My guess (and it is only a guess!) is that the date format being sent by the
crawler is incorrect, so Tomcat burps and spits it out.
It works for your browser as your browser is sending a valid date format.
What is being sent is: 2 Dec 2007 03:08:59 GMT
According to RFC 1123 Section 5.2.14, the date stamp is supposed to be
formatted to the RFC 822 date specification (Section 5) except for the use
of a 4 digit year.
So comparing the spec with what was sent, it looks likes it is upset because
there is no 'day' (e.g. Mon / Tue / Wed etc) component. It should perhaps
read:
Sun 2 Dec 2007 03:08:59 GMT
But as I said, it is only a guess, and I might be way off the mark.
Cheers,
Stuart
