This feed fetcher was sending an If-Modified-Since HTTP header, but it had a rather striking value of 'Wed, 01 Jan 1800 00:00:00 GMT'. Naturally this doesn't match any Last-Modified value my feed has ever provided, and it wouldn't help if I used a time based comparison since all syndication feeds in the world have been changed since 1800.
