Error with "Check by URI" method of RDF Validator

To the RDF Validator team,

There is a problem with this validator that happens quite regularly with the "Check by URI" option. That is: you submit a URI, it validates perfectly, but when you try to validate it again, it produces this error:

"An attempt to load the RDF from URI 'http://www.beta.jdclark.org/meta.rdf' failed. (Undecodable data when reading URI at byte 0 using encoding 'UTF-8'. Please check encoding and encoding declaration of your document.)"

This happens even if you re- submit the *exact* same RDF file without any changes, so you *know* it is perfectly valid.

Otherwise, this is a very useful tool. The "Check by Direct Input" works perfectly every time. Thanks for your efforts in providing it, and thanks in advance for your time in looking into this.

Regards,
