[Zope] redirecting from within an access rule

[Zopista]

Read the minor notes at the bottom of the Site Access docs:
http://www.zope.org/Members/4am/SiteAccess2/vhosting

"The return value of an Access Rule is ignored and discarded. This allows
embedded string comments such as in the examples above, and the use of
<dtml-return " 'ignored' "> to exit the Rule. It also means that if you want
to redirect within an Access Rule, you must use <dtml-raise type="Redirect">
instead of "RESPONSE.redirect()"

Cheers

> hi there

> ----------------------------------
> | host_name, redirect_to
> ----------------------------------
> | "espra.org", "espra.net"
> | "espra.com", "espra.net"
> | "www.espra.org", "espra.net"
> | "www.espra.net", "espra.net"
> | "www.espra.com", "espra.net"
> ----------------------------------
>
> and an access rule:
>
> <dtml-in "redirect_index(HTTP_HOST)">
>   <dtml-unless "redirect_to == ''">
>     <dtml-let to_new_url="_.string.replace(URL0,HTTP_HOST,redirect_to)">
>       <dtml-call "REQUEST.RESPONSE.redirect(to_new_url)">
>     </dtml-let>
>   </dtml-unless>

AccessRule.

instead
