1. @Unstable()

String getAllResponseHeaders ()
@Unstable()

Retrieve all the response headers from a request.

`null` if no headers have been received. For multipart requests, `getAllResponseHeaders` will return the response headers for the current part of the request.

See also HTTP response headers for a list of common response headers.

## Implementation

    @Unstable()
    String getAllResponseHeaders() native;
