Can you be more specific. Which code are you using to redirect to your static page.
Redirect to external hosts is NOT allowed unless you use the -allow_complete_url switch to ad_returnredirect.
See: https://openacs.org/api-doc/proc-view?proc=ad_returnredirect
This is there so that an attacker cannot pass a url with return_url=...
to another site where your site will perform a redirect to the attackers web site.
Only use -allow_complete_url where you trust the value that is passed to ad_returnredirect.
