Cross Site Attacks

I made a new page on the wiki, for detailing the various cross site  
attacks we see, http://www.w3.org/Security/wiki/Cross_Site_Attacks, feel  
free to expand.

I'd like to see a unified apporach to Web security, where a server  
administrator can do a single change to protect the entire server against  
a range of attacks, and page authors don't need to worry about them. The  
page makes the need for a unified approach clear, as of today servers need  
to protect themselves with Origin, CSP, STS, X-Frame-Options,  
Framebusting, Sanitization and more, much of it on every single page. A  
single HTTP header with e.g. a link to a resource file would be easier to  
maintain, save bandwidth, and be extensible for future needs. As is clear  
by e.g. CSP, user agents might need protection against differing attacks,  
a unified solution can also make it easy to allow user agent specific  
instructions.
