Signed HTTP Exchanges (SXG)

Last updated on : 2023-03-20

Note:

Signed HTTP Exchanges (SXG) shows a browser compatibility score of 58. This is a collective score out of 100 to represent browser support of a web technology. The higher this score is, the greater is the browser compatibility. The browser compatibility score is not a 100% reflection for every browser and the web technology support. However, it does give you an estimate on how much you should rely on a particular web technology in terms of browser compatibility.

Overview

Since AMP requires the document host to be the canonical document, one strategy is to use Signed HTTP Exchanges which allow a different origin server to provide a resource via a signed HTTP exchange to display the original URL in the URL bar.
