Hi Vincent, and welcome to the forums!

Here's something I've used to redirect visitors based on IP.  This was to redirect internal network traffic to a different page

On the homepage I had two properties:  internalIPAddresses for a list of IPs to check against, and "internalHomepage", which was a contentpicker with the page to redirect to.  I also hard-coded a regex for an ip range - I got the regex from the tool at http://www.google.com/support/analytics/bin/answer.py?hl=en&answer=55572

Here's the xslt - post back if you want me to go through it in more detail (it's 5:30pm here and i'm leaving!).

p.s. script inside xslt is not best practice! 

Dan

Thanks Dandrayne for the reply!

Is ther a way of doing this only in C#/VB since you say it yourself that having script inside XSLT is not a best practice? And how do I do to make the code execute on the load of the first page?

Thaks again!

Thanks Dan, I'll try this later in my project and I'll let you know if I have questions but it seems pretty clear!

is working on a reply...
