I was recently in a situation where the Internet Explorer proxy settings were enforced via GPO, however I wanted to use seperate proxy settings for my Google Chrome browsing sessions.
Google Chrome doesn’t provide an user interface to change or disable proxy server settings, it uses the proxy settings (amongst other settings) from Internet Explorer.
So how can you change the settings for Chrome and not IE?
Add the ‘–proxy-server=’ parameter to the shortcut you are using to start Chrome. Eg to use the proxy server named proxyname.company.com on port 8080 your shortcut would be:
"C:\Documents and Settings\username\Local Settings\Application Data\Google\Chrome\Application\chrome.exe" --proxy-server=proxyname.company.com:8080
Note – there are 2 ‘-’ symbols before the proxy-server above
