I can't see how this would explain:

1. No entry in the access log for the initial request
2. PHP files being truncated at a different length (3883/3884 bytes)  
than HTML and CSS (4096)

Also, I never saw this problem when a linux machine was running on  
the same network with the same IP. Or am I missing something?
