Squid Cache: Version 3.2.11

The data is from the <access.log> file for a 4 day period.
HIT - 237
MISS - 10522
total - 11347
The stats from <access.log> indicate a 2.2% hit rate. Is this typical?
Seems a bit low.

I loaded the <http://www.squid-cache.org/> page (last 2 lines of
access.log):
1377455358.004 731 192.168.69.115 TCP_REFRESH_UNMODIFIED/304 447 \
  GET http://www.squid-cache.org/Images/img8.gif - \

  GET http://www.squid-cache.org/Images/img7.gif - \
  HIER_DIRECT/198.186.193.234 -

Reloaded the page again:
1377455563.566 268 192.168.69.115 TCP_REFRESH_UNMODIFIED/304 447 \
  GET http://www.squid-cache.org/Images/img8.gif - \

1377455563.571 266 192.168.69.115 TCP_REFRESH_UNMODIFIED/304 446 \
  GET http://www.squid-cache.org/Images/img7.gif - \
  HIER_DIRECT/198.186.193.234 -

I had expected cache hits.

Cache information for squid:
        Hits as % of all requests: 5min: 90.0%, 60min: 6.1%
        Hits as % of bytes sent: 5min: 25.0%, 60min: 1.1%
        Memory hits as % of hit requests: 5min: 0.0%, 60min: 0.0%
        Disk hits as % of hit requests: 5min: 0.0%, 60min: 5.3%
        Storage Swap size: 9132744 KB
        Storage Swap capacity: 17.4% used, 82.6% free
        Storage Mem size: 56628 KB
        Storage Mem capacity: 21.6% used, 78.4% free
        Mean Object Size: 70.26 KB
