Silk Performer 19.0 introduces HTTP/2 replay for web protocol scripts. HTTP/2 is a major revision of the hypertext transfer protocol (HTTP) used in the World Wide Web. It offers a number of improvements over HTTP/1.1, which results in a considerably faster communication between client and server. These improvements include a specific header compression method, the so-called server push feature, and the single-connection approach. Silk Performer now supports these HTTP/2 features for performance and load testing. Using HTTP/2 requires no additional licenses whatsoever.
In addition to facilitating testing of today's modern web applications on the protocol level (HTTP), Silk Performer enables you to use real web browsers to generate load. In addition to Internet Explorer, you can now also use Chrome and Firefox to replay browser-driven scripts. Recording is still Internet Explorer-based and managed through the Browser Application. You can either reuse functional tests that have been created with Silk Test, or you create your browser-driven scripts from scratch within Silk Performer.
