def withPrecompressedMediaTypeSupport: Directive0

Description

Inspects the response entity and adds a Content-Encoding: gzip response header if the entity’s media-type is precompressed with gzip and no Content-Encoding header is present yet.

Example

val svgz = compress("<svg/>", Gzip)
val route =
  withPrecompressedMediaTypeSupport {
    complete(HttpResponse(entity = HttpEntity(`image/svgz`, svgz)))
  }

// tests:
Get("/") ~> route ~> check {
  header[`Content-Encoding`] shouldEqual Some(`Content-Encoding`(gzip))
  mediaType shouldEqual `image/svg+xml`
}
