Basic iRule to Redirect HTTP to HTTPS Custom URI with ? Mark is Failing

Update: We modified the iRule to what the browser is already interpreting and it works now. I don't understand why this works now, but wanted to provide an update for the benifit of others. Thank you Kevin for your insight (trailing / is generally legitimate) to help us resolve this.

So the iRule now reads:

when HTTP_REQUEST {

HTTP::redirect "https:/www.site.com/product/?customer" }
