I'm trying to build a web app that's going to "get" data (more specifically, a string) only from the server, but for use in real-time, but the client isn't going to send anything back to the server (one-way communication)
My plan is that multiple tablets (iPad/Android, via web browser) are going to display information depending on their "role", some may display all or some of this data, depending on the frame. The actual app itself is all set, it's just the communications I'm having difficulty concluding.
Either this will need to be checked rapidly (every half a second) or ideally if the server can "pushes" updates to the client when there's a change. This will take place over LAN and managed via a PC Fusion application that's running on the web server at the same time.
Something like Lacewing would be ideal for this, but unfortunately, this isn't compatible with HTML5 nor available.
I've heard of WebSockets, but I have no clue how this can integrate with the PC Fusion application, if possible at all.
One solution I thought of, which is a really poor implementation... is having the GET object fetch a text file every half a second (using the ?forceload parameter, which is known to duplicate the cache), but so far, doesn't seem to work nor is it efficient nor is it healthy for the web server's storage device rapidly writing / receiving requests to read.
Any suggestions on how to go about this is greatly appreciated!
