Passing data to an object or iframe

[eluser]JWarren[/eluser]
Hi, guys-

This question isn't directly related to CI, but hopefully someone can help me anyway.

I'm trying to insert some code between domains with a little data attached to it. I've thought about an iframe:

Code:

<iframe src="http://someotherdomain.com/class/function"></iframe>

or an object:

Code:

<object data="http://someotherdomain.com/class/function" type="text/html"></object>

My question is how do I pass some data to the page on the other domain? I just need the remote page to know that foo=bar in this case. On another page foo could = bat, etc.

Hopefully that makes sense. Thanks in advance.

How does someotherdomain accept data? URI parameters? Query string?

[eluser]JWarren[/eluser]
I'd rather not use URI parameters or a query string because of special characters. Hopefully this is more clear:

Code:

<object data="http://someotherdomain.com/class/function" type="text/html">
   <param name="css" value="http://domain.com/style.css" />
   <param name="redirect" value="http://domain.com/test.php" />
&lt;/object&gt;

Would there be any way to get the css and redirect values in http://someotherdomain.com/class/function?

Everything available will be in the request header, so check the header. I doubt you'll get anything though.

sophisticated way
XML-RPC and XML-RPC Server Classes

simple way (the other domain use CodeIgniter)

Code:

<frame src="http://someotherdomain.com/class/function/bar"></iframe>
<iframe src="http://someotherdomain.com/class/function/bat"></iframe>

or the other domain don't use CodeIgniter

Code:

<iframe src="http://someotherdomain.com/somepage.php?foo=bar"></iframe>
<iframe src="http://someotherdomain.com/somepage.php?foo=bat"></iframe>
