How to detect Google cache

[kaled]

The javascript content of my pages fail when run from the Google cache. Therefore, I wish to be able to detect when a page is being viewed from the cache. Having looked at the source code of the cache header, I noticed that the <BASE> tag is used to set the base url of the page. I thought that I might be able to use it but I can see no way in javascript to read the BASE value.

Does anyone know how to read the BASE value, or know another way to solve this problem?

Maybe it's easier to read the location string and check for the presence of for example "search?q=cache:".

if (location.href.indexOf("search?q=cache:") > -1) {
// do cache-specific things
} else {
// do regular things
}
