window.open cache problem

Hi all,

I'm using a window.open in a function to open a web page, which displays help for the current page.

The page's url are stored in DB, some pages need authentication.

For these pages:
The first time we call them, the user has to be authenticated but if he closes the page and opens it another time, it's the cached page which is displayed.

I've tried to add the time to the url, in order to not display the cached page...

JavaScript

var oDate = new Date(); 
window.open(url + oDate.getTime());

But the browser is still displaying cached url.

Any idea to resolve this problem

Thanks

In fact i can't modify in the page's that i'm opening with window.open,

this pages already exist , and it's not me who developed them , i have no access to them , i just read the url from DB, and display them

how are you opening them? are the content pages dynamic?

Solution 5

Along with unique url, try giving a new name to window each time you use it.
Something like:

JavaScript

var dt = new Date().toString();
var URLToOpen =  'http://server.com/page1.aspx?TimeStamp=' + dt;
window.open(URLToOpen, 'New Window at:'+dt);
