    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    http := chilkat.NewHttp()

    // Insert your AWS keys here:
    http.SetAwsAccessKey("AWS_ACCESS_KEY")
    http.SetAwsSecretKey("AWS_SECRET_KEY")

    bucketName := "chilkat.ocean"
    objectName := "seahorse.jpg"
    localFilePath := "qa_data/jpg/seahorse.jpg"
    contentType := "image/jpg"

    // User-defined metadata are name/value pairs, and are added to the HTTP request header.
    // Header names must begin with "x-amz-meta-" to distinguish them from other HTTP headers.
    // Note that Amazon S3 stores user-defined metadata keys in lowercase.

    // For example, to add genus=Hippocampus, we do this:
    http.SetRequestHeader("x-amz-meta-genus","Hippocampus")

    // Add a few more user-metadata key pairs.
    http.SetRequestHeader("x-amz-meta-species","big-belly seahorse")
    http.SetRequestHeader("x-amz-meta-habitat","shallow tropical and temperate waters")

    success := http.S3_UploadFile(localFilePath,contentType,bucketName,objectName)

    if success != true {
        fmt.Println(http.LastErrorText())
    }
    else {
        fmt.Println("File uploaded.")
    }
