PS. To play along with the linguistic theme, can you provide a source for the definition of a malformed request? My original intent when using the word malformed was not to invoke it's technical definition but rather it's dictionary definition. But, having said that, I just had a 30 second Google hunt and couldn't find anything to corroborate your position.
