      • cache

        public static Utils.HttpResponseCached cache​(java.net.http.HttpResponse<java.io.InputStream> response)
                                      throws java.io.IOException
        Fully reads the body of the given response and caches it in memory. The returned response has utility methods to view the body (bodyAsUtf8(), bodyAsBytes() and the body() method can be called multiple times, each returning a fresh InputStream that will read from the cached byte array.

        This method is most likely to be used in a diagnostic/logging situtation so that the contents of a response can be viewed without affecting processing. Using this method with a very large body may be problematic in terms of memory use.

        Parameters:
        response - response to cache
        Returns:
        response with a cached body
        Throws:
        java.io.IOException
