We need to create a web-based frontend for displaying some data. The problem is that the data needs to be updated about once a second.
For me as a web-developer the obvious solution is AJAX.
Unfortunately, one of the purposes of this web frontend is to be displayed inside of embedded browser window which is expected to run constantly for months or even years. That’s it, months of work with no restart / refresh.
During testing we ran a proof of concept interface (which requested a simple set of data each 1,5s) in Safari for over a month. During this period of time, the memory usage of Safari raised from ~30 MB to over 100MB.
Thus we’re afraid of stability of such a solution.

I’m wondering if you could recommend us any other technique for this task, possibly with less overhead (when requesting simple sets of data – as in our case – I’m afraid the HTTP headers are very significant part of data)

    I would suggest looking into node.js and the now.js plugging, which allows for realtime updates via websockets. It even has support for older browsers, so if the browser does not support websockets, it will do a fall over to either a comet server implementation, AJAX or an iframe.

    It’s extremely easy to setup on a linux environment, and there’s ample documentation to get you started.

    It works with javascript and runs on the Google V8 javascript engine, so if you’ve ever worked with OOP Javascript, you should be able to pick it up relatively easy.
