- Deployment of HTTP/2 in Cloudways
Cloudways Platform now supports HTTP/2 for SSL-enabled web applications. It is the first major upgrade to the HTTP1.1 protocol which has served the internet world for over 15 years.
Though HTTP/2 is designed to work with HTTP and HTTPS, most of the client web browsers only support it over SSL. That means TLS encryption (SSL) is mandatory for your web applications to get the benefits of HTTP/2.
Deployment of HTTP/2 in Cloudways
By default, HTTP/2 is enabled on all the servers deployed from 22 September 2016. It has to be enabled on all servers that have been deployed before 22 September. You can enable it from the Advanced tab of the Server Settings & Packages section. Once it is enabled, all your SSL-enabled websites hosted on the same server will start supporting HTTP/2.
You can use any third party tool such as this one to verify if your server supports HTTP/2 or not.
- HTTP/2 is now fully supported and available for all browsers. Customers who already have HTTP/2 enabled in their servers, need to disable and re-enable it to update browser support.
- HTTP/2 option can be enabled on a server-wide level. Once it is activated on a server, all the hosted SSL enabled web apps will use HTTP/2.
- Opera Mini, UC Browser, and some Android browsers do not support HTTP/2. To check the complete list of supported and unsupported browsers, click here.
- HTTP/2 is not going to work for browsers that are not supporting NPN/ALPN for HTTP/2. You will continue to access your websites on HTTP/1.1.
