I'm suddenly getting a lot of these errors. Here's an example:

2004/01/14 10:29:35| ctx: exit level 0
2004/01/14 10:29:35| ctx: enter level 0:
2004/01/14 10:29:35| httpProcessReplyHeader: Impossible keep-alive header
from 'http://www.squid-cache.org/Versions/v2/2.5/bugs/'

This is on a Red Hat v9 system, running Squid 2.5S4 and all patches

I think that these many entries in cache.log are the result of applying
the recent squid-2.5.STABLE4-http_workarounds.patch patch.

Anyone else seeing this behavior?
