During maintenance I would like to display a 503 error page on every
request without a redirect. I'd like to use this solution because of
the handling by google bots.
I do know it is possible with apache by altering the htaccess
file (although this is something I learnt from the internet and I didn't test it). My question is if this is possible on a windows server 2008
installation with IIS 7. I suspect it can be done with the URL Rewrite
module but I don't know this for sure and I certainly don't have a clue
how.
Any help on this subject is very welcome!
