Use Only registered users can see links! (ReloadEvery).
Set it to refresh every X seconds, it will ask you once if you really want to keep refreshing a page that requires post data, you tell it yes and it'll keep refreshing it.

JohnsonD, did the solution posted by nerds work?

If you want a website to refresh, hmm lets say after every 5 seconds, then just use the meta refresh tag.

here's the code

<meta http-equiv="refresh" content="600">

You just have to paste it in the head section of your html document. The amount between the content quotation mark is the number of seconds the page should refresh. So changing it to 5 means your page will refresh after every 5 seconds. Hope that make sense.
