I'm trying to delete the cache in 2 ways I found in one of the forums:

1 - wc1.WebView.Reload (true);
2 - EO.Base.Runtime.Shutdown ();

I do not know if the cookies and the cache are being cleaned satisfactorily and if they are the correct methods to do it.

I'm waiting for your help

Hi,

In order to delete everything, you must destroy all WebViews and then delete the cache folder.

To destroy all WebViews, you can call Engine.Stop. Do not call Runtime.Shutdown as you won't be able to create any WebView again until you restart your application. See here for more information about Engine object:

https://www.essentialobjects.com/doc/webbrowser/advanced/engine.aspx

After you stop the engine, you can delete cache folder:

https://www.essentialobjects.com/doc/eo.webengine.engine.cleanupcachefolders_overloads.aspx

Make sure you pass AllVersions to the policy argument.

If you only want to delete cookies, you can use the CookieManager interface:

https://www.essentialobjects.com/doc/eo.webengine.cookiemanager.aspx

This will delete cookie but not cache.

Hope this helps. Please feel free to let us know if you have any more question.

Thanks!

Ok, thank you. I have a other question.

What argument must be passed in policy in cleanupcachefolders?

Excuse me, I have a new question. How can I know if I effectively delete all cookies from the page?

Than you, for your answers.

Hi,

You can use this method to check what cookies are still in the cookie store:

Thanks
