Cookies fail when using URL Frame re-direct

I have a simple html document I have been using for some time on my
(i.e.) abc.com domain that uses cookies. I recently purchased a new
domain name and set up a service to redirect my new domain (i.e.)
xyz.com to a sub-directory of the abc.com domain. In other words, when
someone goes to URL xyz.com, they really end up in abc.com/xyz
directory but the MSIE browser says they are xyz.com.

The problem is that cookies quit working in this setup when I copied
the same HTML document in the /xyz subdirectory that xyz.com now
accesses. I can't set or get a cookie any longer by calling the
document.cookie function from JS any longer. The call does not fail
but the data is always blank. I even tried setting the cookie and from
the next line of code reading it back immediately and it still would
not save the cookie.

Anyone know how to fix this?

I checked the value of location.host, .hostname .pathname,
document.domain and they all indicate I am really at abc.com even
though the address in my IE browser says I am at xyz.com.

Do not use frames for redirection. Use server settings, for example.

You cannot read or change cookies that are from a different second-level
domain. The Same Origin Policy does not care about that you own both
second-level domains; they are different to it, and access is denied.
I even tried setting the cookie and from the next line of code reading
it back immediately and it still would not save the cookie.
That is weird, though. You should be able to set, modify and read the
cookies for the site from the same site. Exactly how are you doing that?
I think it would be best if you posted the URL of your "old" domain.

Probably.

document.domain and they all indicate I am really at abc.com even

document.domain does not indicate anything. Instead, you have to _set_
document.domain in order to access documents or cookies from a different
domain, but the same second-level domain.

Your code, although it is unnecessarily inefficient and badly formatted,
works fine here[1], provided that I remove the newline after the
`return'[2]. Either you have included the newline, thereby returning
`undefined', or you have accidentally blocked cookie access for your new
site.

It would have been nice (and appropriate) if you had referred to anything

OK first thanks for taking time out to help me. I "struggle" with java
script (as you can likely see). I was attempting to set a cookie, in
this example, "test" to a value of "DVT". When I click on URL[2]
above, I see that the cookie is not set:

read cookie test: null
set cookie test : undefined
read cookie test: null

Are you seeing the cookie being set to "DVT" and returning anything on
your browser?

***UPDATE*** !!!! I just tried your link using Firefox instead if IE 6
and I see it fine!

read cookie test: DVT
set cookie test : undefined
read cookie test: DVT2

I guess I have screwed up my IE browser settings somehow. Now just to
figure out what I did!!! I checked Tools, Internet Options, Privacy,
it was set to "Medium". Not sure what else I could have done?

On further test, I can put the same html file in the primary domain and
a copy in the URL Frame pass-to-directory domain, my IE 6 fails to see
the cookie when it is on the URL Frame and handles the cookie as
expected. My IE 6 also fails to set the cookie when I go to your
link:

<URL:http://pointedears.de/scripts/test/dom/cookie-frameset>

Using Firefox, I can see the cookie everywhere I put it, including your
example.

As I said, the domain of the cookie must not be different to the domain
of the document resource that modifies or retrieves it. Since you did/do
not specify the domain, it was/is set automatically in the cookie when the
cookie is set or modified.

bar.example.com cannot retrieve a cookie set by foo.example.com , unless the
cookie was set with "domain=example .com". And a resource at example.net
cannot retrieve a cookie set by a resource at example.com (unless perhaps
the security level is set very low).
My IE 6 also fails to set the cookie when I go to your link:

Why, you should really have a minimum clue about browsers before you start
coding for them:

The "Medium" level in your IE Privacy settings simply prevent these
non-session cookies with unspecified `domain' label from being set (but
they can be read).

Change it to "Low"[1] and these cookies are set without you being asked.
Change it to "User-defined" by activating "Advanced" and "Disable Automatic
Cookie Handling" and you will be asked to set it (and can see the "Details"
of it) unless you set "Accept Always" or "Block Always". AIUI that is
because the other domain is regarded as "third-party provider", so if you
explicitly block those cookies via the "Advanced" dialog, they will never
be set as well.

Tested with IE6 SP1 on Win2k SP4 with .NET 1.1 support [Mozilla/4.0
(compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322)].

Not sure what amok-post means, sorry about whatever i did ... I merely
copied text from one part of this post to the other. Not sure how to
work the controls here? It was just a reference to text above you had
aready entered. Sorry if I caused any problem.

Here is an update. I tried the following link from 4 different
systems. (http://pointedears.de/scripts/test/dom/cookie-frameset)

IE V5 on Windows 2000 - cookie WAS resolved
IE V6 on Windows 2000 - cookie NOT resolved
IE V6 on Windows XP (system A) - cookie NOT resolved
IE V6 on Windows XP (system B) - cookie NOT resolved

Firefox on all OS above - cookie WAS resolved

It is possible all the IE 6 systems I have are at the same fixpack
level. I am investigating that now to see if there is a fix I can
apply. I earlier thought this was isolated to my single main
development system but now I have proved it fails with 3 of my systems
that have IE 6 on them, regardless of the base OS. Firefox works with
any OS (of mine, 2K or XP, that is).

It would be best if you stopped using Google Groups for _posting_ at all.
(However, I am not sure if you are capable of using the controls of a
newsreader if you cannot even use Google Groups properly.)

As if posting a followup to a posting of yourself was not bad enough,
you did not quote anything of what you are referring to, although there
are enough pointers in the newsgroup and in the FAQ already that not only
tell otherwise but also tell how to do it right. And you did it wrong
_again_, although I provided those pointers in my very posting you have
replied to. Again :-(

That is completely useless information because the browser is not the
problem! The browser privacy features and their settings are.
Firefox on all OS above - cookie WAS resolved

You have still not understood (have you even read my posting?). You have to
check the _privacy settings_ in each browser. Probably they are different
by default (maybe influenced by the security fixes), or the feature works
different. It is _not_ a script problem; setting/modifying cookies is not
restricted to scripting. So you are _off topic_ here.
