# HTTP/2 HTTP/2 is a major revision of the HTTP protocol that enables more efficient use of web resources. It is compatible with HTTP/1.1 and does not involve significant changes to basic concepts like HTTP methods, header fields, and status codes. It does however include countless improvements, like the use of a single connection, the compression of header fields, and the server push or cache push service that enables the server to preemptively push information to the client before the client requests it. So, for instance, when an HTML page is requested that is linked to style sheets, images, and other resources, everything is sent together in the first request (multiplexing) rather than having to wait to parse the HTML file. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.transparentedge.eu/getting-started/faq/glosario/http-2.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
