Web frame issue when loading some url

[LaurentGermain]

I use twitter widget, and would like to load the tweet in a separate web frame.

I noticed that web frame doesnt load it.

I noticed that the url returned by the tweeter widget , when loaded in a normal browser is

https://twitter.com/#!/Jean%20de%20K./status/568796822141059072
and it redirects to
https://twitter.com/jnordek/status/568796822141059072

So why is the webframe unable to load it ?

Is it because of special characters , or because of the redirect ?

[ No error appears in the logs]

Hi Laurent,

There are various pages from sites on the Internet that don't load when they're put in an iframe HTML tag (which the WebFrame widget uses).
Twitter also does this, and, while there are various reasons they do this, it would be useful to check this site for additional info:
