I am new to salesforce. I want to use iframe control in visualforce page to load some content from .net. I've used the iframe control as follows
<apex:page >
<apex:iframe frameborder="true" src="http://www.salesforce.com" scrolling="true" id="theIframe"/>
</apex:page>
but it is not loading anything in the iframe control.It is showing only white back ground an also I tried with html iframe control but I got the same response. So can anyone please tell me what am I missing?
