I tracked this down to it sending Expect: 100-continue in the headers of the request it sent to its server. However, it was going via our web proxy at work, which is Squid. Recently I upgraded Squid to 2.7, and this seems to be the cause of the problems. Squid 2.7 is less forgiving about that particular header (which is apparently an RFC violation on the part of the client).

It’s easily fixed by adding ignore_expect_100 on to your Squid configuration.

tail somefile | ccze -A -o noscroll | grep ...

-A makes ccze output ASCII sequences, and -o noscroll turns off the scroll option – whatever that is exactly. The man page says it’s a good idea to turn it off if you’re redirecting the output. Omitting it seems to make the output appear in lumps :)

For example, keep an eye on squid logs omitting all MSN crap:

tail -F access.log | ccze -A -C -o noscroll | grep -v gateway.dll
