Didn't document the submission time, however it was more than eight hours getting a new thread approved. DISMAL!
FWIW, I went through a very large yesterdays log and EVERY
HTTP/1.0 request was for ranges either previously denied or added as harvesters (for lack of a better word).
I've added the line on the site of the large log, and at least it failed to generate a 500 ;)
Will take until tomorrow to determine if it functions as desired.
