AFAIK Squid ignores CR (just another form of whitespace), but it does
not ignore NL.

NL is part of the HTTP protocol and cannot be ignored.

What can be done is to work around the issue by changing Squid to
support HTTP/0.9. However, the HTTP/0.9 support is hidden in the sources
and slightly broken for the moment...

This error is quite often seen with JavaScrip driven ad-banners and
similar things...
