auto refresh page

Question

I need to refresh a web page on the time i get from the user. That's fine. But how i do make

that permanent. Say, the user selects 30secs, and makes it permanent, I need to refresh every

30 secs. I tried $_SESSION, ineffective. Pls don't suggest cookies.

Agreed that cookie must be used, or you must send the selected time back to the server to be stored in session and outputted on subsequent page loads. — JAAulde, Feb 20 '11 at 03:43
In the [javascript cookie library](http://code.google.com/p/cookies/) I wrote, I test by trying to set a cookie and then reading it back. If I don't get back my value, I know cookies are not enabled. I exposed this functionality with a test() method. — JAAulde, Feb 20 '11 at 03:48
If you are asking about cookies being disabled, what about if JS is disabled? It kind of blows the whole thing out of the water. — picus, Feb 20 '11 at 04:01

if cookies disabled, try using localstorage instead...

Srsly? If cookies are disabled then the odds of the user having a browser that implements localstorage or that user has enabled it are basically zero. – Prestaul Feb 20 '11 at 06:47

You'll need to persist the user's selection in some manner.

Cookies, session variable server-side, URL query parameter, localstorage - these are all options.

URL query parameters and SLaks's suggestion of POSTing let you keep different settings for different tabs opened simultaneously, if that matters to you.

EDIT: by URL query parameter I mean redirection, using window.location, to something like http://example.com/foo?refresh=30 and later parsing window.location.searchyourself or using existing code for it.
