Anyone know why when you do a

window.location = "new_url" the http_referer environmental is not set?

i've pretty much got everything working except this little bit..

Is this with just one browser or did you test it on several browsers?

i tried it on mozilla/NS7 and IE5 and IE6

i think it has something to do with the fact that window.location may not be treated the same as a link.. its not actually linking to a page it is just changing the window.location to a new value.

My testing in IE6 shows the behavior you're suspecting. But in Firefox, it runs fine, the referer shows in all instances.

In IE6, using location.href will not set the HTTP_REFERER. Normal links will do. But the funny thing is using window.open(url, '_self') will show the referer but only if the last previously clicked is a normal link.
Try running this simple demo.

page 1:


<html>
<body>
<form>
<input type="button" value="Open using location.href" onclick="location.href='page2.asp'" />
<input type="button" value="Open using window.open(url, _self)" onclick="window.open('page2.asp', '_self')" />
<input type="button" value="Open in new window" onclick="window.open('page2.asp', '_blank')" />
<a href="page2.asp">page 2 link</a>
</form>
</body>
</html>

page2.asp:


<%
response.write "Referer:" & request.servervariables("HTTP_REFERER")
%>

As I suspected (but didn't have the time to check), it's a browser implementation problem. Unfortunately that means you can't do anything to fix it, you have to find a way to work around it.

yea i just ended up passing it through the QUERY_STRING, its a little undesirable but that is the way it goes..

it is essentially just a convienence to be able to send the user back to their original page when they go through some login steps..

Not just convenient, it's polite. Good for you.
