I\'m having some problems passing URL\'s as GET parameter. When I try to access:
http://www.linkebuy.com.br/linkebuy/parceiro?url=http%3A%2F%2Fwww.google.com
If you can't get rid of the restriction you can pass the url in 2 parts like this
http://www.linkebuy.com.br/linkebuy/parceiro?protocol=http&url=www.google.com
And then parse it on your code to make the full url for the redirect.
