Hi,
spiders crawl some dynamic urls in my website (example: http://www.keihome.it/elettrodomestici/cappe/cappa-vision-con-tv-falmec/714/ + http://www.keihome.it/elettrodomestici/cappe/cappa-vision-con-tv-falmec/714/open=true) as different pages, resulting duplicate content of course.
What is syntax for disallow these kind of urls in robots.txt?
Thanks so much
