Hi, many thanks for the replies.
What I've trying to do is re-direct certain groups of users to different sites, all by the same dns name but actually resolved differently. e.g. users all go to my.site.com but it is resolved differently for beta testers, developers, QA etc... A local hosts file is more or less what I'm trying to replicate and was hoping it could be done on the Blackberry OS. I would think they would have a similar concept if not the same idea.
