With a Meta Tag (Plain Html)

Refresh the page at a set interval using a meta tag. Just add the following to the HEAD of your page:

<meta http-equiv="refresh" content="60">

Change the content attribute to the number of seconds you want between each refresh (the tag above will refresh the page every 60 seconds).

With a Link (Javascript)

You can let the user click a link to refresh the page they're on:

<a href="javascript:location.reload()"> Refresh</a>

With a Button (Javascript)

Same as above, except users click a button:

<form> <input type="button" value="Refresh" onclick="location.reload()"> </form>
