FAQ Topic - How do I force a reload from the server/prevent
caching?
-----------------------------------------------------------------------

To reload a page, use location.reload(). However, this depends
upon the cache headers that your server sends. To change this,
you need to alter the server configuration. A quick fix on the
client is to change the page URI so that it contains a unique
element, such as the current time. For example:
` location.replace(location.href+'?d='+new Date().valueOf()) `
If the location.href already contains a Query String, use:
` location.replace(location.href+'&d='+new Date().valueOf()) `
