Problems caused by Windows. open

On page A, there is A windows. click open Link for the first time. After modifying the information in the pop-up window, return to page A. When you click windows on page A again. open Link. in the pop-up window, the data screen is not modified.

So how do I clear the history of window. open?

In fact, it is better to clear the history of windows. open than to clear the content in Response.

Solution: Add the following Code to the Code file on the pop-up page (page B ):

Page_load ()
{
If (! IsPostBack)
{
Response. Clear ();
Response. Cache. SetExpires (DateTime. Now );
Response. CacheControl = "No-Cache ";
Response. AddHeader ("Progma", "No-Cache ");
}
}
