Testing a forum discussion here on the forum with Tammy it seems that one needs to refresh the page after each entry in order to see any reply. Is that true?October 29, 2018 at 11:32 pm #522

who are you asking?October 31, 2018 at 1:40 am #524
Probably yes. Traditionally, the web/WWW works like this: you click links or buttons on a website and the browser asks a server machine what content is stored under it. The server sends the answer data, closes the connection and completely forgets who and that somebody asked for it. In that model, if the client received the answer and something changes later on the server side (caused by a second client or the server itself), the first client not only has no idea, but by requesting the same information a second time, parts of the previous, old answer might remain cached locally to optimize performance and bandwith. PHP is a programming language that allows developers to program a server for this model, WordPress is largely written in PHP.
So I can’t really answer the question and don’t want to investigate, but it pretty much looks like that there is no real-time auto-update, which is not to say that it couldn’t also be a hybrid, because some pages might not expand the page as soon as something new is found on the server and ask for it in short intervals, but instead ask frequently if there have been any updates and then show a notification that the current page is outdated, asking the user to decide if it should be reloaded or if he wants to continue with whatever he was doing at the moment, probably reading, writing or copying that should not be disturbed by something magically happening and interrupting the current activity, diverting attention/focus and what not.November 1, 2018 at 1:08 am #531
If content of a website changes as a client is watching in a browser window, the new content may not appear until the web page is refresher. Newer apps can tell if the source doc has changed if you are on a fast connection, might alert you if your browser settings allow it. I use Firefox QuantumNovember 2, 2018 at 9:20 pm #534
Good summary, Alex, that’s what I’m saying in more detail. Note that it has nothing to do with the newness or oldness of a website: it’s a different technological approach, so it can very well make sense to build non-auto-updating websites today, or have pretty old websites into which some auto-updating was inserted here and there. Question is where it is needed. If this forum should be (ab?)used for real-time live conversation, it might not be designed to help with that too much.November 11, 2018 at 3:39 pm #619
I need live updating on my weather channel and it’s cool the way FaceBook does it with a signalling gif. someone is typing…. an insult or constructive insight. You’re getting this message because you opted in to grant our deep learning robot access to all your meta data. Haaaaaa Ha Ha
