问题:

I have an iframe in my web page. It works fine in FF and Chrome but not in Safari (I'm using Safari 6.0)

This is my code:

<html>  
    <head>  
        <title>Pengower</title>     
    </head>  
    <body>  
        <div id="container">  
            <iframe name="news" id="news"   
                src="http://www.penapplications.net/ImogenApps/?Pengower:CRM:Pengower_News">  
            </iframe>  
       </div><!--end container div-->  
    </body>  
</html>

Funny thing is that, if I access the src url and then access the iframe page, then the iframe shows the content properly, but if I just access the iframe page without accessing the src url page before, it does not show the content.

Any ideas?

回答1:

The iframe seems to be redirecting to a mediating page (penDummyLogon.aspx) which attempts to automatically submit a form to the final page (main.aspx) and set a cookie.

Since this method of setting a cookie seems to have been blocked in the recent Safari versions, the user arrives at the final page without the cookie. main.aspx doesn't seem to be able to handle the missing cookie, and as a result its expected content doesn't load.
