OK, you have a refresh with period zero (which doesn't work
reliably, so a period of one second would be better), and
you would like the validator to validate the page /after/
the refresh/redirect has taken place.  Supposing that the
page to which you redirect has a further refresh/redirect,
this time with a delay of two seconds; would you like the
validator to validate /that/ page rather than either of
the first two ?  And if that page too has a refresh/redirect
with an even greater delay, would you like the validator
to follow that one as well ?  If so, what is your cut-off point ?
How long should the delay be in a refresh/redirect before you
don't expect the validator to follow it ?

You will need to be aware of which server you are using; for at
last three common server, there was already a link to the documentation
for that server in the original answer to which you refer; if you
are using a less-common server, you will need to consult the
server documentation.  For a simple overview of what your
server will need to accomplish (but with no guidance as to how
to achieve it), see
