Redirection to customised url for cms restriction

[Former Member]

I have created a Restriction which extends AbstractRestriction. I have an evaluator implementing CMSRestrictionEvaluator.
I want to apply the restriction to a page. For example Product Page.

The restriction to the page is true and should redirect the page to a login page.
It always redirects to a generic error page, whilst I want the redirection to a specific to say login page.

How to achieve redirection to a specific page?

Thanks In Advance.
