> Rationale: we currently have 2 security filters, which among other things 
> have duplicated configuration (the "callback", which presents the client with 
> a login form). On top of this, with MAGNOLIA-3858, we realized there are 
> cases where we also need to handle an {{AccessDeniedException}} which can be 
> thrown between those two filters (i.e from a servlet; example: the RSS 
> servlet, which wraps an {{AccessDeniedException}} when the content it needs 
> to access to generate a feed is not authorized for the current user).
> Implementation:
> * the 2 existing filters will not execute the callbacks anymore. They will 
> merely set a {{401}} or {{403}} http code in the response.
> * the new filter, place in front of those two, will check the response's 
> status, as well as catch {{AccessDeniedException}}s that might have been 
> thrown down the filter chain, and execute an appropriate callback.
> This way, any component down the filter chain can set a {{401}} or {{403}} 
> response code, or throw an {{AccessDeniedException}}, and we'll send an 
> appropriate response to the user.
> TBD: how does this behave if rendering has begun ? It is expected that an 
> {{AccessDeniedException}} or other exception happening at that level would 
> not be let up the chain.
