Sub Server_HandleRequest (Request As ServletRequest, Response As ServletResponse)

      'add for permission:
    Public rp As RuntimePermissions
    rp.CheckAndRequest("READ_EXTERNAL_STORAGE")
    rp.CheckAndRequest("WRITE_EXTERNAL_STORAGE")
    rp.CheckAndRequest("ACCESS_FINE_LOCATION")
    rp.CheckAndRequest("INTERNET")
      'end add for permission
  

    Try
        Log("Client: " & Request.RemoteAddress)
        Log(Request.RequestURI) 'handle the request based on the URL
        Select True
            Case Request.RequestURI = "/"
                HandleMainPage (Response)
            Case Request.RequestURI.StartsWith("/list/")
                HandleList (Request, Response)
            Case Request.RequestURI.StartsWith("/download/")
                SetContentType(Request.RequestURI, Response)
                Response.SendFile("", DecodePath(Request.RequestURI.SubString(9)))
            Case Request.RequestURI.StartsWith("/upload/")
                HandleUpload(Request, Response)
            Case Else
                'send a file as a response (this section is enough in order to host a site)
                SetContentType(Request.RequestURI, Response)
                Response.SendFile(File.DirAssets, DecodePath(Request.RequestURI.SubString(1)))
        End Select
    Catch
