[opencms-dev] Modifying a 302 Response?

[a.westermann at alkacon.com]

Hi John,

thanks for the clarification. In that case I'd go another route. It is 
no good idea to change the resource loader of the external link resource 
type (BTW: you could write your own and use it in your configuration).

I'd create a new resource type for external links with a field for that 
link. Then I have the jsp that is assigned to it's template-elements 
property and could execute whatever code I'd like whenever resources of 
that type are requested (e.g. do a dynamic redirect).

Kind Regards,
Achim.
