Hi Guys,

I have these two JavaScript codes:

HTML Code:

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

This one ^ refreshes a page when clicked

HTML Code:

<a href="#" onclick="history.go(-1);return false;">< Go Back</a>

And this one ^ takes the clicker back to the page they were previously viewing

I was wondering if both these pieces of code could be combined so that when the "Go Back" link is clicked the previous page would come back but refreshed.

Nope.
Because "history.go(-1)" is the same as clicking the back button in your browser.

It reload the url previously opened, and use it's cache.
The only way to defeat cache, would be a real link, with a seed to force refetching.
like

HTML Code:

<html>
<script type="text/javascript">
seed=new Date().getTime()
</script>
<a href=javascript:top.location="http://www.whatever.com/pageX.html?seed="+seed>Go back</a>
</html>

No, that just refreshes the same page it doesn't take one back.

There's no "refresh the same page".
The fact is that your browser is either intellignent enough to recognize the page should still be the same, or too dumb to see that the given parameter should force it to refresh it.

There is no magical trick here. It can be a server configuration too, that cause this problem.
If this don't work, then you will need to use something more radical,like an empty post to get back on that page.

What is the result if you have a normal link, rather than some javascript to get you back to your page ?

Alright thanks. I initially needed this for a "captcha error message" related issue but I got the code for that fixed so I no longer need this.
