[squid-users] FD error in reverse proxy mode

Hello, we are trying to reverse-proxy a WebDAV-based application in a
split-DNS setup. The application seems to work; however we see error
messages in the cache log like (data partly altered)

I suppose this is the reply to the forwarded request? If so, what should
this message tell me?

Any ideas?

Best regards,
