How can i show Sitecore maintenance page on Sitecore website while deployment.
We have load balancer environment with 6 CD servers but our client is not agree to remove CD server one by one from load balancer and add them again on load balancer after deployment, because this way it will increase deployment time from two hour to 4 hours.
I know there is a way to use
app_offline.htm and put it on root of website directory but by using this our website warm up script is also not running as expected as script is also getting
And also while deployment our Sitecore website is not responding otherwise we could use Sitecore pipeline to achieve this.
Please suggest what else we can do here to achieve this.
