After installing AT pro and setting up date basis config all my sites go down with a too many redirect message. after deling the HTTP to HTTPS redirection from the htaccess the problem is over.. but what is going wrong in my setup?
##### HTTP to HTTPS redirection
## Since you have enabled HSTS the first redirection rule will instruct the browser to visit the HTTPS version of your
## site. This prevents unsafe redirections through HTTP.
RewriteCond %{HTTPS} !=on [OR]
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule .* https://domainname.com%{REQUEST_URI} [L,R=301]
