Incognito ?

Hi,

Is there a way to use DCEF4 in the Chrome's 'Incognito window' mode ?

Thanks

Hi,

Use in-memory cache to be in incognito mode.

You only need to leave GlobalCEFApp.cache blank, which is the default value, to use in-memory cache and navigate in incognito mode.

Usually i set GlobalCEFApp.Cache with the same value of GlobalCEFApp.Cookies ; what is the actually difference between them ?

[salvadordf]

The cache is a collection of databases and other files used by the browser to avoid downloading all the web page contents every time you navigate to that site.

Usually, the cookies are also stored inside the cache directory and they have small pieces of information like user IDs, session IDs, etc.

CEF4Delphi has the GlobalCEFApp.cache property where you can select the cache directory or leave it blank to use "in-memory" cache.

In case you need to store the cookies in a different directory than the cache then you can select it in the GlobalCEFApp.cookies property. If you leave GlobalCEFApp.cookies blank then CEF3 will store the cookies in the cache directory or "in-memory", depending on the GlobalCEFApp.cache value.

So if i set .Cookies but not .Cache, i still will remain logged in the sites i visited, but in incognito mode ?

I just tested that combination and the browser is still logged in because the cookies are stored in the directory specified in GlobalCEFApp.cookies.

In incognito mode the browser should not store : browsing history, cookies and site data, or information entered in forms. The browser should delete all that information when the user closes the application and it shouldn't be available to other "normal mode" browsers open in the same application.

If an application sets GlobalCEFApp.cookies then those cookies are available the next time you run that app and that breaks the "incognito mode" definition.

You need to leave GlobalCEFApp.cache and GlobalCEFApp.cookies blank to be incognito mode... or create a new browser using a new request context with the cache and cookies parameters blank.
