depends on the end site os and httpd and reference site (indexer) os and httpd.
some are case sensitive (unix and linux clones for instance) and some are not (windows).
clearly if both work for the same effective url its case intensive situation.
if one works over the other its case sensitive.
to know that first is hard, you can not assume prior to request (headers can give you some information).
in the past the back end probed multiple times to different outcomes, this led to detection and or banning of client to multiple request in short secession.
