I have two pages namely www.abc.com/pg1.aspx
and www.abc.com/pg2.aspx
pg1.aspx
response.redirect("www.abc.com/pg2.aspx");
pg2.aspx
string url_refer = Request.UrlReferrer.ToString();
UrlReferrer
is working fine.
pg1.aspx
<a href='#' onclick=\"window.open('www.abc.com/pg2.aspx', 'windowname2', 'width=1014, height=709, screenX=1, left=1, screenY=1, top=1, status=no, menubar=no, resizable=no, toolbar=no'); return false;\">
pg2.aspx
string url_refer = Request.UrlReferrer.ToString();
UrlReferrer
is NULL
I googled for the solution. but none of them are leading to the solution i want.
My problem is if the window is with no menubar, status or toolbar, UrlReferrer
is NULL
if not, UrlReferrer
has the previous page's URL.
I also tried url_refer = Request.ServerVariables["HTTP_REFERER"].ToString();
instead of string url_refer = Request.UrlReferrer.ToString();
.
the result is the same.
Any solution?
My solution is to take it from "document.referrer"
document.addEventListener('DOMContentLoaded', function () {
document.getElementById('hfUrlReferrer').value = document.referrer;
})
<a href="javascript:void(0);" onClick="MyWindow=window.open('','gallery','location=no,directories=no,menubar=no,scrollbars=no,width=550,height=550');MyWindow.location.href='yoururl.html;MyWindow.focus(); return false;">
The trick is to use location.href which does record the referer in IE.
I found this great workaround on a forum, and adapted it slightly.
Put this code at the top of your page:
<script language="JavaScript">
function goTo(url){
var link = document.getElementById("link");
link.href = url;
link.click();
}
</script>
<a id="link" target="_blank" href="javascript:void(0)"
style="visibility:hidden;position:absolute;"></a>
...and then build your links like this:
<input type="button" value=google onclick="goTo('http://www.google.com')">
What you're doing is creating an invisible <a>
element, then using javascript to change that element's address, and programatically "click" it.
There's no easy answer to this - in general, the UrlReferrer
is a browser-specific behaviour. Chrome, for instance, can process this differently than Internet Explorer.
If you are doing the referring yourself then you'll be best off passing a querystring parameter or using session state to identify the referring URL.
I'm not sure.. but I found out..
Session is not working if we call a new page using Javascripts.
I was told that all session values are reset on a new page which is called using javascripts.
As an alternative for my question, I used QueryString.
I really don't want the users to see the URL but I already hide the URL with javascript.
So, I have no problem using querystring, right?
Does anyone hava a better solution?
