* Decompressing gzip-compressed request bodies.
* Automatically logging all request bodies.

## Handling custom request body encodings

Let's see how to make use of a custom `Request` subclass to decompress gzip requests.

And an `APIRoute` subclass to use that custom request class.

### Create a custom `GzipRequest` class

			<param name="module.zip.version" value="${opensearch.version}" />
		</antcall>

		<antcall target="remove.jars" />
	</target>

	<target name="install.module">
		<get dest="${target.dir}">
			<url url="${repo.url}/${module.groupId}/${module.name.prefix}${module.name}/${module.version}/${module.name.prefix}${module.name}-${module.zip.version}.zip" />
		</get>

The main limitation is that to update or delete content of a file inside a ZIP file the entire ZIP file must be replaced.

## How to enable S3 ZIP behavior ?

Ensure to set the following header `x-minio-extract` to `true` in your S3 requests.

## How to access to files inside a ZIP archive

- UTF-8 is the only encoding type the Select API supports.
- GZIP or BZIP2 - CSV and JSON files can be compressed using GZIP, BZIP2, [ZSTD](https://facebook.github.io/zstd/), and streaming formats of [LZ4](https://lz4.github.io/lz4/), [S2](https://github.com/klauspost/compress/tree/master/s2#s2-compression) and [SNAPPY](http://google.github.io/snappy/).

    // the transfer stream.

    }

Wenn ein eingehender Request nicht korrekt validiert wird, wird eine „400“-Response gesendet.

## `GZipMiddleware`

Verarbeitet GZip-Responses für alle Requests, die `"gzip"` im `Accept-Encoding`-Header enthalten.

Diese Middleware verarbeitet sowohl Standard- als auch Streaming-Responses.
