Comment #5 on issue 18396 by berendjanwever: about:blank tabs via  
window.open should display origin in the address bar
http://code.google.com/p/chromium/issues/detail?id=18396

@madeleine.pultier: (regarding your second point) AFAIK the about:blank  
page is
treated as being in the same origin as its creator and all cross-origin  
checks apply.
That means the about:blank page has the same access rights as the page that  
created
it, so any communication between http and https would not need  
this "trick". If I am
mistaken and you know of a way to bypass cross-origin checks in Chrome  
please show me
how: I cannot reproduce this.

Also, any ssl page can "give" data to any other page in a number of ways:  
eg. by
creating a FORM that POSTs the data to any other site. I assume you meant  
to say that
an http page can "take" data from an https page. That would be considered a  
cross-
origin problem but, as I mentioned, I cannot reproduce this with the given  
example.

@lcamtuf/mal: don't forget to include all origin information (protocol,  
port). Would
we open up a can of IDN-spoofing? How would we treat (bad) https  
connections? Do we
color the address bar similar to the opener page?
