Re: Apple Push Notification Servers (APNS)

I have seen this error which I thought was related to a keep-alive error (* as the last parameter) in the HTTP client implementation, but it appears you are not using that option. My work-around was to just retry the request which seemed to work. Might be worth a try. John DeSoi, Ph.D. > On

Apple Push Notification Servers (APNS)

Hello, Anyone having any luck sending notifications to Apple's Push Notification Servers? I'm getting mixed results when I try to POST the HTTP REQUEST: in v16.4: Error code: 49 SSL internal error : error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca component: 'srvr' in v17.0:

Re: Socket Communication

Polling does not have to be an immediate request/response. See long polling: https://www.pubnub.com/blog/2014-12-01-http-long-polling/ With websockets your are going to have a connection open all the time anyway, so long polling is no more resource intensive. I would not use it for the public w

Re: Socket Communication

That looks pretty cool. I've built a chat app on PubNub a while ago. ( www.pubnub.com) I haven't looked back at PubNub recently - Pusher looks like they may have built out a few more tools. In both cases they have very generous free programs. On Tue, Jan 15, 2019 at 1:57 PM Welsh Harris via 4D_T

This is worth a look: https://pusher.com - setup a pusher channel in your pusher account - browsers subscribe to a pusher channel - 4D makes and http request to the pusher channel - boom all the browser who have subscribed get the message Welsh **

RE: Socket Communication

John, Thanks... This is just "polling" logic and won't work for us, which is why I am asking about web sockets. In our world, when a machine goes down we have to immediately contact the browser managing the machine. In polling logic, it would mean we only check every X interval. Before anyo

RE: Socket Communication

John, Not sure I understand what you are saying, would you be able to provide me with a high level overview of what you are thinking? Our Server will be performing analytics' and at some point it will trap on a condition that needs to be communicated to the shop floor. For example, a machine

Re: Socket Communication

Do you really need the ability for the server to send data asynchronously to the client (browser)? If not, then HTTP should work and is already supported in the browser and on 4D Server. John DeSoi, Ph.D. > On Jan 15, 2019, at 1:30 PM, Stephen J. Orth via 4D_Tech > <4d_tech@lists.4d.com> wrot

Hi, I have a client running a 4D application for about 50+ users. A recent audit has thrown up a request to be able to track change made to each field in the database. The audit would encompass the date and time of change, the field changed and the before and after values. Does anyone know if a
