Javascript question

[Beej]

Let me start by saying that my understanding of Javascript is almost 0 :)

I'm trying to write a function that will take the user back to the page they came from, but not their cached version. Since
window.location = history.back()
takes the user back, and
window.location = 'www.whatever.com'
takes the user to whatever.com, I figure I can do somehting like this:
var location = history.back()
window.location = location
but that (and all variations on it I can think of) doesn't work. Any ideas?

On the page you don't want cached (previous page) put this meta tag.

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">

The first line looks after all other browsers and the second IE5+.

Try JavaScript:history.go(-1)

Sorry, I should have said, I need this to be Javascript. I can't put anything Im my meta tags (don't ask why, I just can't :D)

verbose101 - I'm not sure what you mean, do I put that in the meta tag or inside a javascript function?

For example, your "back" button could be...

<a href="JavaScript:history.go(-1)">Back</a>

(without the space between java & script, for some reason the forum puts the space in :confused: )

As Lz0 said, in the pages you do not want cached as far is I know you have to use the META tags, then the javascript funtion to go back.

So you need to go back one page using JavaScript? That would be easy - as follows:

<a href="java script:history.go(-1)">Back</a>

But you want to get the page unchached but you don't have access to the page to insert this into it:

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
