# 75.17 启用HTTP响应压缩

Jetty，Tomcat和Undertow支持HTTP响应压缩，你可以通过设置`server.compression.enabled`启用它：

```
server.compression.enabled=true
```

默认情况下，响应信息长度至少2048字节才能触发压缩，通过`server.compression.min-response-size`属性可以改变该长度。另外，只有响应的content type为以下其中之一时才压缩：

* `text/html`
* `text/xml`
* `text/plain`
* `text/css`

你可以通过`server.compression.mime-types`属性配置。

## 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, and the optional `goal` query parameter:

```
GET https://jack80342.gitbook.io/spring-boot/ix.-how-to-guides/75.-embedded-web-servers/75.17-enable-http-response-compression.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
