Re: [Spyce-users] Bailing out on an external redirect

[Rimon B. <ba...@cs...>]

Sure...
  return
or
  raise spyceDone

See: http://spyce.sourceforge.net/doc-runtime_except.html.

Design rationale: The reason that this method continues to process the
page (unlike the other redirects) is because it is often the case that
people would like to display a page when this kind of redirect is used.
The SourceForge download page, for example, uses this trick. They show you
all the mirrors, and then redirect to the download file on the appropriate
mirror after a few seconds. Other sites use the same technique to display
a 'thank you' page, or the like.

Incidentally, why are you using an redirect.externalRefresh(), and not a
redirect.external(), or a redirect.internal()? The redirect.external()
will change the url, just like the externalRefresh().

All the best,
Rimon.
