Description

[Eugene Savitsky]

look at this page. There should be 3 banner, but in Moz we see only 
scrollbars...

This going on with all http://www.linkexchange.ru:8080 banners.

With this are affected most of .ru sites.

Must I post here a list of sites this is affected on?

2/3 .ru sites (and 90% of most popular .ru sites) have this issue... Please do 
smth with this for RTM! 

To get attention I raise the priority and severity.

todays branch build is capable of displaying the images in attachment 17695 [details] if
you first go into 4.x and use view image to get the URL and paste the URL into
Mozilla. So the problem is not the RLE images. The problem must either be the
iframes used to layout the image or converting the absolute URL used to load the
image. Reassigning to pollmann to investigate further.

This looks like a server-side problem with linkexchange.ru to me.

Nav does not display the iframes (<iframe> is not implemented in Nav, so it
displays the alternate content inside the <iframe> tag), but in IE, they look
fine.  Here's an example URL:

http://www.linkexchange.ru/cgi-bin/erle.cgi?23385?2179

when I load this URL with Moz (or even directly telnetting to the server and
requesting it, I get an HTTP redirect to:

http://rle-mirror.agtel.net/users/expelled.gif

That is a blank GIF image, which is correctly displayed in Nav as a blank
rectangle.  When I fetch this with IE, a page is loaded.  My guess is that the
site is doing User-Agent sniffing and showing us the page it gives to "unknown"
user agents.

Marking this evangwanted.  I don't think I'll have time to do a full
investigation for RTM, but am pretty sure that this can be corrected very simply
on the server side.

Comment 8

[Kevin McCluskey (gone)]

Marking rtm-, based on Eric's comments that this is a server-side browser
sniffing issue.

It's pretty easy, really...
It turned-out that NN6 does not submit an http referrer for iframe request. 
With no referrer at all, the algorithm that filters illegal activities in our 
banner network comes into play - and redirection to expelled.gif occures 
instead of standard text/html output.

Thanks [e-mail], I'll look into why we aren't sending the referrer along
with requests for iframes.  :)

Comment 11

[Eugene Savitsky]

Now all looks fine.
Was this fixed in mozilla or on linkexchange.ru?

Comment 12

[Eugene Savitsky]

It is defenetly not fixed in mozilla since NS6 also shows all banners.
Linkexchange did smth on they engine.

Attachment: test case

Working now.  To verify, open up the test case.  You should see:

A page with a black box.  Inside the black box, it should say:

"http://bugzilla.mozilla.org/showattachment.cgi?attach_id=30018 sent you to me."

In Netscape 6, which had this bug, the black box will say: "I dunno."
