Creating Google Chrome shortcut with --disable-web-security

First search Run, then try this:

chrome.exe --user-data-dir="C:/Chrome dev session" --disable-web-security 

Just clone the shortcut for chrome you have on your desktop, and then in the shortcut properties add the parameter --disable-web-security (and --user-data-dir) at the end of chrome executable path

e.g

"C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="C:\tmpChromeSession"

Edit #1 : I changed google chrome path, the old one was not correct. I just tried it on XP with fresh Chrome installed, but i got a error message that this flag is not supported.
