Ah - that makes sense, and my apologies to the previous poster who
mentioned 304s as this is probably what he meant too, but I didn't
understand him.
However, sensible as it sounds, it's not what's happening :-( My
original post was incorrect (it was late :-( ) and the count of 200
result codes I gave was in fact the count of ALL matches in the logs
for the redirected files on serverB, which did contain a significant
number of 304s. Apologies for the confusion, but the basic question
remains the same - why do 25% of the requesters to the original
server not follow the redirect?
