I've seen similar things, I suspect that these are probes from a couple of 
possible places:
- content distribution networks (akamai and the like)
- caching networks (squid)
- ad networks (doubleclick and the like)

Most of the time when I saw these the source address turned out to be part of
the address space of one of the above.

However I noticed the source address on this on was part of a netblock owned
by the brearley school in new york. So it's sort of suspicious....
