“HTTP/1.1 301 Moved Permanently” and “Location => http://domain.com/wp-content/cache/supercache/domain.com/index”. Here is results:

First http header check result

Date => Thu, 26 May 2016 05:45:37 GMT
Server => Apache
Vary => Cookie,Accept-Encoding
Link => ; rel=”https://api.w.org/”
Cache-Control => max-age=86400
Content-Length => 27624
Connection => close
Content-Type => text/html; charset=”UTF-8″

Second http header check result
HTTP/1.1 301 Moved Permanently =>
Date => Thu, 26 May 2016 05:46:37 GMT
Server => Apache
Location => http://domain.com/wp-content/cache/supercache/domain.com/index
