Deploying changes without Site Downtime Started By Rajesh Hi, Whenever we need to deploy any changes that require a new dll or an updated dll to be placed in the production environment, our site takes 20 minutes to start as all the dlls are being rebuilt etc. This creates a 20 minutes downtime for us and has become a problem to keep the server down for so long. I am sure there must be a better way to deploy that I am overlooking. Can someone guide me on how one needs to do this so that the site downtime, if any, is minimal Thanks	2	1671	2	4/6/2021 6:55 AM by Rajesh

The fix was to change this in AJAX.c...	1	1828	0	3/6/2021 8:45 AM by Andreas

Urgent attention! A new change in the GTMetrix reports Started By Armin Rahimian Recently, the GTMetrix analys technic has been changed. It's similar to Google reports. In the best conditions, a new DNN Installation With compression gets Rank E. Wonderfull Look at Following Images: If you hover your mouse over the images above, I will explain which server each one is hosted on. Different servers in Canada, England and Iran. Two of these are newly installed versions and even one of them is css/js compressed which should get an A rating.	2	2110	1	11/18/2020 1:06 AM by Armin Rahimian
