Hi
The problem is:
I want to allow partially display my page in iframed version, but only
for one address.
top page ( http://location1/top.html) code: <iframe name='iframed'
id='iframed' src='http://location2/iframe.html'></iframe>
I cannot call any function from top or parent in case of security
errors.
I tried to:
1. check if this.name == 'iframed'
This worked unless one click to any link in the iframed page (the
name changes)
2. check top.location value
Breaks in case of security bug
Is there any way to send any information to iframed page or receive any
information about top page?
Of course where page location servers are different ?

Keep in mind that it's rediculously easy to thwart this if someone is
trying to, but it will stop the automated ones:
<iframe name='iframed'
id='iframed'
src='http://location2/iframe.html?inm yframe=true'></iframe>
Then parse out the querystring and make sure it says what you want it
to say.
It's possible that you could use document.referr er instead, but I'm not
sure all the implications of that with how your iframed page moves.

Exactly. Search the archives for "Same Origin Policy".
Is there any way to send any information to iframed page or receive any
information about top page?
Generally, no. Especially, the protocols, the second-level domains, and the
port addresses of the two URI references must be the same, or you will have
to use a signed script to request the required privileges (or lower the
security level of the user agent, but that is not recommended).
Of course where page location servers are different ?
The physical location does not matter, the logical one (addressing) does.

Hi everyone,
I am trying to create a site with pages containing iframes. This is the
first time I've used inline frames and am still struggling with the concept.
This site will have 10 pages and so far I have created 20 files, each page
having to use a pair of files. One file for the actual page, and one file
for the content of the inline frame.
It sounds bloody silly to me but then again I am only a beginner at web

to change or disappear.
For example, a HTML file has a table with 3 rows, the first and...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
