Disable CORS policy in Chrome

To initiate a new Chrome session with CORS disabled on Windows for testing purposes, you can use either of the following commands:

Launch the Command Prompt (cmd) terminal and navigate to the directory where the chrome.exe is situated.

Typically, it can be found in either the Program Files or Program Files (x86) directories. Executing the following commands will initiate a new Chrome window with the security policy disabled:

C:\Users\shahpreetk> cd C:\Program Files\Google\Chrome\Application

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

OR

C:\Users\shahpreetk> cd C:\Program Files (x86)\Google\Chrome\Application

⁠
C:\Program Files (x86)\Google\Chrome\Application\> ⁠ chrome.exe --user-data-dir="C:/temp/chrome" --disable-web-security ⁠

For Mac, you can achieve the same testing setup with the following commands:

• To open a new Chrome session/window with CORS disabled:

open -na "Google Chrome" --args --user-data-dir=/tmp/temporary-chrome-profile-dir --disable-web-security

• To open a new Chrome tab in an open Chrome session/window with CORS disabled:

open -a "Google Chrome" --args --disable-web-security --user-data-dir
