Redirect issue view to request view if user has only portal access to that request

[David Lee]

I am trying to find a way to automatically redirect users away from the issue type view to the portal view if they have no agent access to that project. 

Eg user trying to view

jira.company.com/browse/XYZ-1234 but they are not an agent, therefore, receive "cannot find this issue" screen

They are able to view request in portal view eg.

jira.company.com/servicedesk/customer/portal/1/XYZ-1234

The users are agents in other projects so trying to find a clean way to redirect to portal URL.
