96485 - referrer not sent for images loaded via javascript new Image()

Status: RESOLVED FIXED

(Core :: Layout: Images, Video, and HTML Frames, defect)

[Chris Casciano]

I have a little stat tracking "bug" embedded in the page give above. It's just
used to record the site visitor's viewable browser dimentions. While viewing the
apache log files to extract the info I noticed that Mozilla was the only browser
where the referrer field was *not* valued. This was the case with the following
user agent strings:

Mozilla/5.0 (Macintosh; N; PPC; en-US; m18) Gecko/20010131 Netscape6/6.01

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; m18) Gecko/20010131 Netscape6/6.01

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.3) Gecko/20010801

Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.3+) Gecko/20010806

[only a few sorry, i just created this tracker]
This information is valued for ever other user agent that has made the image
request [IE4,5 & 6 & NN4.x on both mac and pc]

---

The code that is being exected is as follows:

function triggerbug() {
var iWidth = (window.innerWidth) ? window.innerWidth : document.body.offsetWidth;
var iHeight = (window.innerHeight) ? window.innerHeight :
document.body.offsetHeight;

var bug = new Image();
bug.src = "bug.gif?clientw=" + iWidth + "&clienth=" + iHeight;
}

---

now, the linked site doesn't require referrer to function, it's just something i
noticed cause i was in my logs. That's not to say other sites do not rely on
this functionality to work.

Is this still an issue?  There was a recent fix to send referer for image in a
much wider set of cases....

I don't believe it is, usless this fix landed extremely recently (read post
0.9.9). Looking at some recent data written by the script at
http://placenamehere.com/2001-09-11/ I see the following in my logs:

XXX.XXX.XXX.XXX - - [11/Mar/2002:21:58:31 -0500] "GET

In contrast here is what IE is giving me in the same scenario:

XXX.XXX.XXX.XXX - - [18/Mar/2002:14:18:07 -0500] "GET
/2001-09-11/bug.gif?clientw=1024&clienth=603 HTTP/1.0" 200 43
"http://www.placenamehere.com/2001-09-11/" "Mozilla/4.0 (compatible; MSIE 6.0;
Windows NT 5.1; Q312461)"
