# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.transparentedge.eu/getting-started/faq/glosario/http-2.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
