| I have a webApp built with struts. There's one normal page in it(name it as pageA)
I browse pageA in Internet Explorer, after that if I use the "back" or "forward" button to get to pageA again, IE don't retrieve it again from the web server, it just uses the cache page.
The question is: I have a link on pageA like this.
<a href=" javascript:doOpenWin('1','1','1','2','',
'MT0000000007');"><span class="ja12">hoso</span></a>
If I click the link and pops up a window, after that if I use "back" and "forward" go get to pageA, IE WILL retrieve it again from the server. Why? What causes IE to retrieve it again from web server? Just one click?
Any one can help me out?
the javascript definition is listed below:
function doOpenWin(param1, param2, param3, param4, param5, param6){
var param = "..." + param1 + "&R_PAGE_NUM=" + param2 + "&R_CATEGORY_NUM=" + param3 + "&R_SETSUMONN_NUM=" + param4 + "&R_HOSOKU_ID=" + param5+ "&R_SOZAI_ID=" + param6;
openWindow(param + '&newWindow=true','_blank',600,500);
}
function openWindow(url,target,width,height){
url = getURLForGet(url);
return window.open(url,target," menubar=no,scrollbars=yes,resizable=yes,
width=" + width + ",height=" + height);
}
function getURLForGet( url ){
var os = getOsName( ) ;
var browser = getBrowserName( ) ;
var version = getBrowserVersion( ).charAt( 0 ) ;
var str = url;
if ( os == "Windows" && browser == "Netscape" && version == 4)
{
if (str.indexOf("?") == -1) {
str += "?";
} else {
str += "&";
}
dt = new Date();
str += dt.getTime();
return str;
}else{
return url;
}
