Is there any way via window.open to have it pass the referring url?

It seems to do it on some IE's and always in Firefox. So far I think my only way is to do a window.open and then have a gateway page but I didn't want to do that if I didnt have to.

Thanks

If I"m understanding you right, couldn't you just append the current url to the new page you are opening, as a parameter?

The page I am opening wants to make sure its coming from www.domain.com but if you use window.open that is blank for some reason in most browsers, firefox seems to pass it and some pc's here do too.

If you rely on the browser, I think you are out of luck....

"The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted."

Thus, I think the only 100% method would be to pass it as a parameter...it does mean the page being opened would have to accept and read that parameter though.

Note: If you pass it as a param, it loses any real use security-wise...as anyone could pass whatever info they want.

You'd have to use some encryption.

thanks

That's what I got from a few google searches, just wanted to make sure there wasn't some other hack to make it work.

you could do it with a pretty simple javascript..

put this in the popup window..

Code:

if(window.opener.document.location.href!="http://www.yourdomain.com/somepage.html") {
    alert("bahh.. you didn't come here from the correct page");
}
