If you mean what I think you mean, your posts show up instantaneously as soon as they're uploaded to the server. It's just your end, which I can't do much about unfortunately. If your post doesn't show up on your end, the best thing to do is clear cache and refresh (keyboard shortcut: ctrl+shft+r).
very neat trick. Thanks for the info. Also I don't save anything into a cache for my browser. It's turned off.
