Passing Data to Another Server, but Load it via iFrame

I need to have website A have a simple form, that submits data to website B, but have the response appear on website A via an iFrame from website B. This is possible?

<FORM TARGET="MyIframe"    ACTION="http://www.siteB.com/page.php">
<!--- inputs here --->
</form>

<iframe id=”MyIframe” name="MyIframe" ></iframe>


if fom is submited the data will be submitted to http://www.siteB.com/page.php and show in iframe “MyIframe”
