AJAX Mash-up Sites?

[VUNETdotUS]

My research I did a while ago showed there was no possibility to get
web page content from a third-party website with AJAX only, without
using a server side technology. Now I have to re-investigate this case
and look for a workaround, perhaps, to allow client side to get the
content of the external page, living on another server. In case you
are wondering, there is no content stealing: both parties agree to
exchange data.
Please, advise if you know of any examples, links or suggestion as to
how a client can request external page content.
Thanks.

If the third party can be trusted you can have them provide the data
as a piece of JavaScript, and pass data to them in the query string:

<script type="text/javascript">
function myFunction(third_party_code) {
// etc
}
</script>
<script src="http://example.com/foo/?hello=world">
// which would contain something like:
myFunction({ foo: 'bar', baz: [1,2,3,4] });
</script>

The script element that sourced the third party data could be
dynamically generated.

That's not true.

The same way it requests any other content. It only fails if a user's
browser settings restrict cross-domain requests. Since this may rule
it out for your particular application, you can use dynamically
created script elements as described in a previous post.

Hi,

As you have seen in the other responses, it will be tricky: changing
policy in browser, or using an iframe.
Which brings me to: WHY do you avoid serverside scripting?
Getting a random page via AJAX is simple WITH serverside scripting.

In PHP it would be simple as:

<?php
$requestedPage = $_POST["requestedpage"];
echo file_get_contents($requestedPage);
?>

What is wrong with a little serverside help?

It is a very high traffic problem.
