This is a mix of FD 26 which is running along fine apparently with
google requests and and FD 40 which is having problems.

If we assume that FD 40 is the client connection to Squid and FD 26 is
the connection to google. This appears to be requests being fetched from
google successfully, and the client disconnecting suddenly ~30 seconds
after the last one is sent.

Conclusion: persistent client connections with a 30 second timeout?
normal, no problems there.

NP: some bits earlier in your cache.log should indicate how FD 40/26
were setup to check that assumption.

Hmm, what is this "all_ip" thing? an attempt at redefining locally
what IPs exist on the Internet? (which is what "all" means in
squid-speak).

*Ten minutes later* an ICY request on FD 13 aborted by the client
browser 6 seconds after starting to stream. As far as Squid is aware it
was fine. Again this appears to be normal for the Squid section of the
transfer.

This looks all the world to me like something in the user agent
screwing up.

Can you please check this with 3.1 or later which support ICY
(SHOUTcast) protocol relay better. The 2.7 workaround is a bit
experimental.

I've tested the 3.1 support a year ago with WinAmp, RealPlayer, and
MediaPlayer with good results. There is always the possibility they may
have changed the details and broken things since then though.
