There are some script that validate web-pages. Used by few top Russian search web-sites. There, page 'index' is not acceptable (406) but page index.html is ok. Why so? Is it correct? How about content negotiating?
Samples:
error 406 -- http://www.be1.ru/stat/?url=http://www.orw...u/library/index
good one -- http://www.be1.ru/stat/?url=http://www.orw...rary/index.html
Basic question: is this script good or not? If yes, what should I do with this 406?
Thank in advance,
Dag
