Thank you for your response, Eliezer.
I added the logformat command that you suggested. I needed to modify it
slightly, since I'm running squid 3.1 (I changed <a to <A and removed
%>eui). An example of what I am seeing in /var/log/squid/access.log is:
1457630282.410 490 172.31.169.175 TCP_MISS/200 4621 GET
https://<server>/tw4/index.php/Two
- FIRST_UP_PARENT/127.0.0.1 text/html Q-CC: "max-age=0" "max-age=0" Q-P:
"-" "-" REP-CC: "s-maxage=18000, must-revalidate, max-age=0" REP-EXP: "-"
VARY: "-"
I am testing from a desktop browser (Chrome and IE). I am entering the page
address directly rather than doing a browser refresh. I am watching
/var/log/squid/access.log and /var/log/httpd/access.log to see what
requests squid and apache are receiving.
Thank you,
Cindy
