i am trying to find out if it's viable to use a http status when the page has been requested but the readystate times out indifinately at 1 so if this happen i could update a div showing a consequent message like "your request has timeout please try again" just like on a classic html environment you get:

"The connection to the server was reset while the page was loading.,The site could be temporarily unavailable or too busy. Try again in a few
moments. etc.."

so what http status should be used for this?
