[squid-users] Squid & MRTG OID config

hi guys..

i am running Squid-2.4 STABLE3 on SuSE 8.0 Pro...
squid supports SNMP and SNMP connections on port
3401.. i have configured community strings and any
other SNMP details pertinent to squid.. and it's
working fine... i have tested it with the line:
snmpwalk -p 3401 hostname communitystring
.1.3.6.1.4.1.3495.1.1 and it gives the correct
feedback as explained in the squid FAQ..

i have loaded the MIB file and used it against some
MRTG configs for squid.. and they work, except for
two, which are very important stats.. as shown by the
error below...

SNMP Error:
Received SNMP response with error code
  error status: noSuchName
  index 2 (OID: 1.3.6.1.4.1.3495.1.5.2.1.2)
SNMPv1_Session (remote host: "192.168.0.2"
[192.168.0.2].3401)
                  community: "string"
                 request ID: 1052264831
                PDU bufsize: 8000 bytes
                    timeout: 2s
                    retries: 5
                    backoff: 1)

SNMPGET Problem for cacheHttpHits
cacheClientHttpRequests on string@192.168.0.2:3401
 at ./mrtg line 1491
WARNING: Expected a number but got ''
WARNING: Expected a number but got ''

everything else works fine.. and i get stats for
cache_mem........ cpu usage etc.. except these two
here... could there be an updated MIB file for
squid..?..

attached is a text file of the MRTG config file for
squid... please advise...

all help appreciated...
