That will work with "standard includes."  Just set the [tmp] scratch
before including the <head> block.  If you use the code, presented above,
the <meta> tag won't be added unless the variable is present.

The answer to your concern would be to set the [tmp autorefresh]
value on the error page and nowhere else; as long as the [if] is
present in the <head> section, no other pages will be affected.

I don't see why the [tag] should fail; I haven't looked into it.  If I
needed to do this, I'd stick with the <meta> tag anyway.

I doubt that you want the Interchange page server to sleep for x
seconds, potentially keeping other users waiting.  Also, a sleeping
process will act like a dead/looping process - prompting Interchange's
housekeeping routine to hammer it if it stays asleep for too long.

Safe prevents you from shooting yourself in the foot.  Long live Safe. :-)

I'd use the <meta> tag, yes.
