Refresh

The Refresh response header directs a web browser to either refresh or redirect the page when a specified amount of time has passed after the page was fully loaded. It is exactly equivalent to using <meta http-equiv="refresh" content="..."> in HTML.

Note: Even though it's present in the HTTP response, the Refresh header is still handled by the HTML loading machinery and happens after HTTP or JavaScript redirects. See redirection order of precedence for more information.

Header type Response header
Forbidden header name no

Syntax

http
Refresh: <time>
Refresh: <time>, url=<url>
Refresh: <time>; url=<url>
<time>

A non-negative number of seconds after which to refresh the page. Fractional parts are recognized but ignored; you should only specify integers.

<url> Optional

If present, the browser will redirect to the specified URL instead of refreshing with the current URL. This URL can be quoted or unquoted. The url= prefix is case-insensitive and optional.

Examples

This header will cause the browser to refresh the page 5 seconds after it is fully loaded (that is, after the load event):

http
Refresh: 5

This header will cause the browser to redirect to the homepage 5 seconds after the page is fully loaded:

http
Refresh: 5; url=https://example.com/

See the http-equiv="refresh" attribute in the HTML reference for important information about accessibility implications of automatic redirects.
