iOS Desktop View

The current way of requesting desktop version of websites by bringing up the keyboard after tapping the address bar - then clicking the desktop icon, is not working on all the sites I tried on. Try google docs and other websites like securitykiss.com. The same websites can in fact be brought up in desktop version using safari on same iOS, but remains mobile version in aloha using the above method.

Could you please fix this? Is there an alternative method? This is very important in some of the sites I visit often. Thanks very much!
