Just wanted to make the point that although Opera does this by default, even in its state it identifies itself as Opera if the detection routine is thourough enough. This rules out most JS and simple software, but some more advanced tools finds out about this double identity easily and reflect their results thus. For example, my Opera 7.23 identified as Explorer; UAG = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0) Opera 7.23 [en] There is enough info there to find out what is really browsing your page, but most scripts/functions that tries to work this out does it left to right looking for the first instance of certain patters, missing the important right-most info. Anyways, just some added inflation. Alexander -- http://shelter.nu/
