Select this option when you want to pass sub page paths even for internal redirection with the same website.
Passing sub page paths for internal redirection within the same website can cause looping and is automatically detected in our system and stopped if the redirect is within a website.
However there are cases when this needs to be used and this option will force it.
Your Website URL is http://mywebsite.com and you have set it up to redirect all Canadian visitors to http://mywebsite/ca which is a sub section of your website.
If a visitor arrived on your website directly onto a particular product e.g. http://mywebsite.com/shop/productA then 'shop/productA ' is the sub page path.
This path can be passed onto the final Redirect URL, so the visitor will get redirected to http://mywebsite.com/ca/shop/productA
