How does it work and what does it do?
Software has been tested with log files from Squid 2.5 STABLE 5 for
Windows NT 4.0/2000/XP/2003

Open a log file and start analysis. Wait for the results which are shown
in an table (detailled view) and in a text field (summary). You may then
export the results to a file.
Squideff checks every line of the Squid log file and assigns occurrence
and traffic to the different cache codes. Afterwards, traffic from cache
and internet are calculated.

For this project I have decided to work with signed 64-bit integers in order
to work with large numbers (?2^63..2^63?1). Despite that, it may be possible
that values exceed this range. In that case, please tell me (not that I know
what to do about it).


The following codes are calculated as data coming from the cache:
- TCP_HIT
- TCP_REFRESH_HIT
- TCP_REF_FAIL_HIT
- TCP_IMS_HIT
- TCP_MEM_HIT
- TCP_OFFLINE_HIT
- UDP_HIT

The following codes are calculated as data coming from the internet:
- TCP_MISS
- TCP_REFRESH_MISS
- TCP_CLIENT_REFRESH_MISS
- TCP_SWAPFAIL_MISS
- UDP_MISS

The rest is shown as not considered for efficiency:
- TCP_NEGATIVE_HIT
- TCP_DENIED
- UDP_DENIED
- UDP_INVALID
- UDP_MISS_NOFETCH
- NONE
