Interceptors can be chained. Suppose you have both a compressing interceptor and a checksumming interceptor: you'll need to decide whether data is compressed and then checksummed, or checksummed and then compressed. OkHttp uses lists to track interceptors, and interceptors are called in order.

        then:

MinIO server allows streaming compression to ensure efficient disk space usage.
Compression happens inflight, i.e objects are compressed before being written to disk(s).
MinIO uses [`klauspost/compress/s2`](https://github.com/klauspost/compress/tree/master/s2)
streaming compression due to its stability and performance.

		// This is the first write; send a clear code.
		// https://www.w3.org/Graphics/GIF/spec-gif89a.txt Appendix F
		// "Variable-Length-Code LZW Compression" says that "Encoders should
		// output a Clear code as the first code of each image data stream".
		//
		// LZW compression isn't only used by GIF, but it's cheap to follow
		// that directive unconditionally.

## Version 4.5.0-RC1

_2020-03-17_

**This release candidate turns on web socket compression.**

The [spec][rfc_7692] includes a sophisticated mechanism for client and server to negotiate
compression features. We strive to offer great performance in our default configuration and so we're
