GoogleChromePortable Settings

This concerns settings using GoogleChromePortable on a USB memory stick.

If I have GoogleChromePortable.ini set to:

RunLocally=false
CacheInTemp=false

will this insure that NOTHING--for example the the browser history--will be written to the user's computer.

Further, if I have those settings set as shown and the USB stick runs out of writable memory, what will the browser do?

If I want the cache to not get any content is it correct to add this to do so?

AdditionalParameters= --disk-cache-size=0

Other than using "incognito" settings is there any way to disable History or to limit its length in time or bytes?

Thanks, Mark
