A/B redirect with query string

[#1]

Hi there,

I have two versions of a site

http://site.com/a

http://site.com/b

I want to use Adobe Target to send 50% of traffic that lands on site.com/a to site.com/b ...

However, I want anyone that comes to site.com/a?query=string to stay on site.com/a ... I only want people that land on site.com/a WITHOUT any query string to be considered for redirection.

How can I set this up in Adobe Target?

Thanks!
