IE7 key:value pairs persist across single pages but not entire domain

[leereamsnyder]

It's entirely possible that I'm missing something here, but in IE7 the key:value pairs are not persisting across the entire domain.

They are persisting across page refreshes and browser restarts for individual pages, but as soon as I go to a different page on the same domain, the data is no longer there.

Here's what I'm doing. I'm trying to store a setting across pages. After I load your script, I test if a localStorage value exists already. If it doesn't exist, then I create/set the value:

var settingExists = typeof localStorage.getItem('theKey') === "string";

if ( !settingExists ) {
  localStorage.setItem("theKey", "the value");
}

That works great on a page refresh. But when I go to a different page on the same domain, localStorage.getItem('theKey') returns null (where I would expect it to be set already from the previous page).

Am I missing something really basic here?

Thanks for bringing this up, I was under the impression that it did work across a domain but I will have to go back and take another look.

Was this ever addressed?

I also use this behavior in general, but the approach is useless because IE userData is per folder. This restricts the url structure a lot. My workaround is to have a single Iframe that contains the userData. This way, I have a shared localStorage. The only drawback is that I have to rely on an iframe load event that will usually fire after the main page load event.
