Testing http2

http2 is the latest protocol  everyone is migrating on it due to its reliability and speed. So my client asked me the same to enable it for his server, i had to enable http2 protocol on one of my client’s dedicated server. After enabling it i faced very strange issue that took my couple of hours figuring out the main cause.

I enabled http2 and then tried to access web site with local chrome browser (Version 65.0.3325.181 (Official Build) (64-bit)) it returned http/1.1 all the time in network tab. Then i tried accessing it on my remote desktop server having windows 2012 standard version i saw all the things work fine and in network tab i saw h2 which means it is working.

So i searched on google and came to the conclusion it is either network (ISP), antivirus or firewall which is blocking the access via http2 and reverting back to http/1.1 protocol. Here are 2 URLs to check for http2 support locally and on web server.
