OkHttp Zstandard (zstd) Integration
===================================

This module enables [Zstandard (zstd)][1] response compression in addition to Gzip, as long as
the `Accept-Encoding` header is not otherwise set. Web servers must be configured to return zstd
responses.

Note that zstd is not used for sending requests.

```java
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(CompressionInterceptor(Zstd, Gzip))
  .build();

  id("okhttp.quality-conventions")
  id("okhttp.testing-conventions")
}

project.applyOsgi(
  "Export-Package: okhttp3.zstd",
  "Automatic-Module-Name: okhttp3.zstd",
  "Bundle-SymbolicName: com.squareup.okhttp3.zstd",
)

dependencies {
  "friendsApi"(projects.okhttp)
  implementation(libs.square.zstd.kmp.okio)

  testImplementation(projects.okhttpBrotli)
  testImplementation(projects.okhttpTestingSupport)

 *  New: The `okhttp-zstd` module negotiates [Zstandard (zstd)][zstd] compression with servers that
    support it. It integrates a new (unstable) [ZSTD-KMP] library, also from Square. Enable it like
    this:

    ```kotlin
    val client = OkHttpClient.Builder()
      .addInterceptor(CompressionInterceptor(Zstd, Gzip))
      .build()
    ```
