Hello to all,
I have implemented a service on VPS AMAZON to handle customer requests, activities, and location of external staff.
Here the link: www.mardomcat.it

The solution is open to possible integrations of third-party.

The solution uses:
-AMAZON virtual server
-App MARDOM STAC (android). link
-App CUSTOMER SUPPORT (android/apple), to be given to customers. links: apple android
Server and Apps uses GOOGLE DATASTORE as data repository.

The solution is able to receive the data sent by other apps

Send message:

'Message structure:
    'LLL        >>  3 characters. lenght next field. example: 001
    'FIELD TYPE >>  1 character
    'LLL        >>  3 characters. lenght next field
    'FIELD NAME >>  field name
    'LLL        >>  3 characters. lenght next field
    'DATA       >>  field content

    'legenda FIELD TYPE
    '0 text
    '1 number
    '2 date
    '3 hour
    '4 barcode


    Dim  job4 As HttpJob

    job4.Initialize("richiestasup1",Me)
    Dim account As String="xxxxx"
    Dim passwordOperator As String ="xxxxx"
    Dim dateNow As String="21/09/2017"
    Dim hourNow As String="14:54"
    Dim customerId As String="unique customer id"
    Dim titleRequest As String="xxxxx"
    Dim message1 As String="xxxxx"
    Dim message2 As String="xxxxx"
    Dim messagen As String="xxxxx"
    Dim nameApp As String="name of your app"

    job4.Download2("http://mardomstac1.appspot.com/", Array As String("par0", "richiestasup1", _
    "par1",account, "par2",passwordOperator, "par3",message1 & message2 & messagen, "par4",dateNow, _
    "par5", hourNow, "par6",customerId, "par7",nameApp, "par8",titleRequest))

server response codes:

Sub jobdone (job As HttpJob)
Select job.JobName

    Case "richiestasup1"
        Dim response As String=""
        Dim idMessage As String=""
        If job.Success = True Then
            If job.GetString.Length >= 3 Then  response    = job.GetString.SubString2(0,3)
            If job.GetString.Length >  3 Then  idMessage   = job.GetString.SubString(3)
        End If

        If response ="101" Then
            Log("ERROR: account unknown")
        End If

        If response ="" Then
            Log("ERROR")
        End If

        If response ="100" Then
            Log("Message received. Id message: " &idMessage)
        End If

End Select
End Sub

@juvanum I don't seem to be able to open the website. I get in the browser:

b4j_ws.3.01.min.js:1 WebSocket connection to 'ws://www.mardomcat.it/ws/alfa' failed: Error during WebSocket handshake: 'Sec-WebSocket-Accept' header is missing

Is it possible you are behind a proxy? I have experienced a similar error when trying to setup HAProxy and some load balancing. But I blamed my inexperience with writing the HAProxy script for this.

@alwaysbusy I don't know what to say...

Working fine here. Tested with FireFox and Chrome.

Have you tried to clear cache? And with a different browser?

 

[alwaysbusy]

I'll try it again when I'm at home. Our network guy here at work is a freak so who knows what he has done over here. Don't worry about it, if it works for you guys, I'm sure it is on my end!

Just did a VPN to my home and tried it there. No problem at all! Sorry for being a cause of panic
