Thanks for your efforts, Tim! I'll try this patch.

Mike (Sweet), what is your take on this? I'd tried 1.3.10 without this patch - and got lots of 'W [dd/mmm/yyyy:hh:mm:ss +zzzz] Request from "a.b.c.d" using invalid Host: field "cups.x.y.z"' messages in 'error_log'. We use a CNAME to assign the name 'cups.x.y.z' to a print server which has a name of its own (different virtual servers may be the print server at different times, e.g. when the original is being updated or having hardware maintenance), but always point the clients at 'cups.x.y.z'. I looked for an explanation and found Tim's bug report.

I found that adding the 'ServerAlias' directive (which doesn't appear in http://www.cups.org/documentation.php/doc-1.4/ref-cupsd-conf.html at this time, by the way) which Tim mentions in https://bugzilla.redhat.com/show_bug.cgi?id=497301 still didn't give me a working system. I got a "400" error when I try to look at the CUPS scheduler's web pages. Will try the patch.

I'm hoping that 1.3.10 will get rid of the many "E [dd/mm/yyyy:hh:mm:ss +zzzz] Bad request line" messages (followed by a request line which is a jumble of apparently random characters) that plague our 1.3.9 'error_log' file - and also fix other reported problems.
