If you are confused whether your hosting server (or any other website) is using Apache or Nginx or any other platform, then here is a small trick to figure it out easily.
1. Open your desired website using Google Chrome browser.
2. Right-click the logo and select the option “Inspect”. Then, navigate to the “Network” tab. Refresh the page if it takes time to load. In the “Name” column, select your website link (here ‘hellboundbloggers.com’).
Under the ‘Headers’ tab, you’ll find the ‘server’ details, here you can see it’s displayed as ‘nginx’. So here is your answer!
###Adobe - Apache Web Server
###Microsoft - Internet Information Services (IIS) Web Server
