See CefRequestHandler::GetCookieManager():

Code: Select all

  ///
  // Called on the IO thread to retrieve the cookie manager. |main_url| is the
  // URL of the top-level frame. Cookies managers can be unique per browser or
  // shared across multiple browsers. The global cookie manager will be used if
  // this method returns NULL.
  ///
  /*--cef()--*/
  virtual CefRefPtr<CefCookieManager> GetCookieManager(
      CefRefPtr<CefBrowser> browser,
      const CefString& main_url) { return NULL; }


Return CefCookieManager::CreateManager() for each browser.

Thanks a lot

Code: Select all

 CefRefPtr<CefCookieManager> ClientHandler::GetCookieManager(
      CefRefPtr<CefBrowser> browser,
      const CefString& main_url){
        std::string cache_path = "K:/cef_cache/";// should be retrived from browser host setting, but i will find how later
        CefString cookie_path = cache_path+ "cookie_"+std::to_string((long double)browser->GetIdentifier());         
        return CefCookieManager::CreateManager( cookie_path, false);
   }

This code create a cookie path for every browser with the cache_path like : K:/cef_cache/cookie_1 , K:/cef_cache/cookie_2 , K:/cef_cache/cookie_3 ...

But it crach just after the return , any idea ?

Try to return an in-memory cookie manager and see if that makes any difference.

Same result, i dont know what path the CefCookieManager::CreateManager is expecting.

also it's strange that the browser will create a new CefCookieManager in every request, no? the session must be the same along the user connection.

And i check the cache folder K:\cef_cache\ i found a new empty folder cookie_1 but not the others cookie_2 cookie_3 ...cookie_6

GetCookieManager will be called every time the cookie manager is needed, not just once per browser. If you wish to always return the same cookie manager for a given browser you need to manage that in your handler implementation.

OK thanks, so you confirm that if a new CefCookieManager is returned on every request, the browser will not keep the session.

But could any one tell me how correctly return a new CefCookieManager without craching the application?

It's probably not a crash but instead a debug assertion because you're specifying the same path for multiple calls to CreateManager.

I think that you should *not* return 2 different cookie managers for the same browser.
