Um, okay...

... from the MIB.txt for 3.0 the OID *.3495.1.4.1 appears to be IP cache.
Which makes *.6 misses mean a remote DNS lookup performed and *.3 hit a DNS
record stored from previous lookup.

From the 3.0 mib.txt the HTTP stats are at OID *.3495.1.3.2.1.2 (TCP_HIT /
TCP_*_HIT). Misses are not reported, but total HTTP requests
(*.3495.1.3.2.1.1) and errors (*.3495.1.3.2.1.3) are.
