这是网络上传的客户端程序，如何在其中加入异步传输代码，让后台进行传输，不影响前台操作？
Dim msg As String = "head=" & head & "&body=" & body & "&updates=" & updates
Dim req = System.Net.WebRequest.Create("https://www.xxx.xyz/insertage.php")
req.Method = "POST"
req.Timeout = 10000
req.C
req.UserAgent = "Mozilla/5.0 (Windows NT 6.3; rv:66.0) Gecko/20100101 Firefox/66.0"
Dim aryBuf As Byte() = Encoding.GetEncoding("utf-8").GetBytes(msg)
req.ContentLength = aryBuf.Length
Dim writer = req.GetRequestStream()
writer.Write(aryBuf, 0, aryBuf.Length)
writer.Close()
writer.Dispose()
