Base rewrite condition on external web page

["Robert Webb" <rwebb@xxxxxxxxxxxx>]

I am setting up a maintenance web page but I need to control two proxies 
from one location. I am looking for a way to have my proxy server poll a web 
page on a different web server and allow a rewrite based on the the http 
status code.

Example, on one of the two servers, I use a variable set toggle maintenance 
on or off. That covers the first proxy server. I would like to have the 
second proxy server to be able to poll a specific URI on the first server 
that when in maintenance mode, the first server responds with a specific 
http status code. Then based on that status code, the second server will 
redirect to a maintenance.html page.

I am just not sure how to call the external page and set a variable for the 
rewrite condition in the second server.


Is this even possible?

Thanks,

Robert
