Have you ever heard about SPDY protocol before? In case you don’t know, it’s a networking protocol, which was developed by Google to transport contents of websites. This protocol is helping to reduce page load and improve the web security in Google Chrome.
Through the compression, the SPDY protocol will help us to lessen the size of web pages to load faster, as well as improve the security of it, especially in e-commerce stores.
At the earlier of 2015, Google announced they would not support SPDY protocol anymore in Google Chrome. The reason is that the HTTP/2 standard is better, faster and more secure than the SPDY protocol. That’s also the reason why Google want to withdraw and replace it with HTTP/2 protocol.
According to Google and Mozilla, Google has removed SPDY support in the Chrome version 51. Mozilla also removed this protocol in the Firefox version 50. The only disadvantage of the SPDY protocol is that sometimes, it causes a few annoying errors, such as Err_SPDY_Protocol_Error error. It’s one of the several annoying errors in Google Chrome that is related to the SPDY protocol.
We wouldn’t deny that this protocol from Google was helping us to speed up website load times for a while before the HTTP/2 standard release. However, with the disadvantage of it, most of the internet browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge or Opera are abandoned it already. Instead, they moved to use HTTP/2 as the replacement solution, which is faster and of course, more secure than the SPDY protocol.

Actually, most of the browsers don’t abandon the SPDY protocol yet. They are just upgraded to the new version. The current version of SPDY is 4.0 alpha3. It is more closely aligned with HTTP/2 standard and has a new stream flow control with the HTTP/2 draft.
