Error storage when going offline

[taitems]

Is the onbeforeunload event soon enough to fire a request if the interval hasn't fired yet?

If it's not, store to localStorage and send next time the page is loaded. How long before you invalidate an error? Revisit the site/page after 7 days and the error is no longer relevant? Drop it?

Yeah, let's go 7 days.

This is probably relevant to my other question about firing off all the requests as one or individually, as far as I know, requests can persist if fired onbeforeunload.

The Paul Irish polyfill will shine here btw.
