@RTDP
Downgrading from subdomain to fqdn works still in Chrome. It’s switching subdomains / domains that does not work:

> document.domain
“www.bing.com”
> document.domain = ‘bing.com’
“bing.com”
> document.domain = ‘fff.bing.com’
Error: SECURITY_ERR: DOM Exception 18

In other words, you can change it only one way – simplify (strip subs). Adding / changing into child subs no worky.

New idea: if you want cross subdomain (www.domain.com and sub.domain.com) and you are working on apache. things can get a lot easier. if a subdomain actually is a subdirectory in public_html (sub.domain.com = http://www.domain.com/sub/. so if you have ajax.domain.com/?request=subject…you can do something like this: http://www.domain.com/ajax/?request=subject

works like a charm for me, and no stupid hacks, proxies or difficult things to do for just a few Ajax

What a great work around. I’ve been banging my head trying to figure out why this was failing.
Sub-domain can’t be different. ARGH!!!

this workaround seems to do the trick. THX!

Sorry about the double post, need to format this stuff :

-domain.com
__|-search
__|-dev
____|-subdomain1
____|-subdomain2

(_ = space)

Hi !
Great stuff… But I have a problem.
It is working well with a page under subdomain1.dev.domain.com containing an iframe with a page under subdomain2.dev.domain.com.
It does not work (or I don’t know how to make it work) with a page under subdomain1.dev.domain.com containing an iframe with a page under search.domain.com.

I think there is a domain problem :

-domain.com
|-search
|-dev
|-subdomain1
|-subdomain2

And pages under subdomain1 will never be able to access to pages under search…

If you have any idea…

Oops! Okay, I'm wrong. It DOES work! And work it does! Holy Crap. What a great solution. It works in Safari 3, and FireFox 3, but it is critically important that you set document.domain in both DOM's that you want to have talking to each other.

What I was trying was the first DOM was src'd at blah.site.com and the iframe was at subdomain.blah.site.com, and I was only setting document.domain in the DOM of the iframe to try to match the src'd URL of the main page. This does not work. Even though the main page is src'd at blah.site.com you still have to explicitly set document.domain='blah.site.com' or it won't work.

Yay!

Greg.

The problem is that it _doesn't_ work. At least, it doesn't work in Safari. I haven't tested in FireFox yet, but I'm not confident.

If this only works in IE, then I think it was important that this is mentioned.

Greg.
