[Adam Marshall]

we think the limit is tested further up the chain than CHS but aren't sure.

| I'm not quite sure what you are referring to when you say "site info".
| I'm also not sure where the limits are tested.  Obviously CHS tests the
| limits, but the actual testing may be in deeper, as part of the file
| upload method used.  I was using RSF and the Apache commons upload
| package.  Generally HTTP doesn't care
