[squid-users] "deep" analysis of some request

Is there a way to analyze somehow deeper what's going on with this?

tss# grep -c 'http://ecs.amazonaws.com/onca/xml?' access.log
3065
tss# grep 'http://ecs.amazonaws.com/onca/xml?' access.log | tail -1
66.55.138.70 - - [08/Sep/2011:18:59:26 +0000] "GET
http://ecs.amazonaws.com/onca/xml? HTTP/1.1" 200 135861 "-"
"Mozilla/4.1" TCP_MISS:DIRECT
tss#

I'd like to capture it somehow so I can look what kind of request is that.
