We are currently on Sitecore 9.0.2 rev. 180604 and have a website
www.abc.com and it has a web page called
www.abc.com/a and this is the page that relies on back end systems. These systems have a scheduled maintenance every week on a fixed timeframe for example like every Saturday 2am to 2:30am EST.
During this time, part of the webpage flow does not work but the page will be up and running so we decided that during this timeframe anyone trying to access the URL
www.abc.com/a, I would like to intercept them with a maintenance page
www.abc.com/Maintainace.htm and once the maintenance timeframe is finished I would like the URL work the way it is.
What is the best way to approach this scenario? can we implement a IIS redirect on the URL based upon the timeframe? any help is much appreciated.
Thank you in advance.
