Lost cookie problem

[PioneerDk]

1.Visit the site's cookie read and write function is no problem!
2.If you do not close this browser , the cookie read - write function is no problem !
3.Just close this browser , access the same page and don ' t read the cookie information previously saved ! I set DcefBApp.CefCache is a folder that exists , but this folder generates a lot of files .

What parameters do I need to design to solve this problem?

How to write cookies to Dcefbrowser after the website has been logged in?

[PioneerDk]

js,Dcefbrowser is used like any other browser, but only closed and then opened, missing cookies.

DcefBApp.CefPersistSessionCookies:= true; It doesn't work.
