In the latest CEF4Delphi updates I've uploaded some new demos that might be interesting.
- CookieVisitor : Using TCefCookieManagerRef to read all the cookies
- PostDataInspector : Using an alternative method to read the POST data before is sent.
I had to rename some of them for clarity, sorry.

I added the word 'Event' to all the TCefRenderProcessHandlerOwn functions and now they are easier to identify.
TCefCustomRenderProcessHandler.OnCustomMessage is now called TCefCustomRenderProcessHandler.OnProcessMessageReceivedEvent
TCefCustomRenderProcessHandler.OnWebKitReady is now called TCefCustomRenderProcessHandler.OnWebKitInitializedEvent
TCefCustomRenderProcessHandler.OnBeforeBrowserNavigation is now called TCefCustomRenderProcessHandler.OnBeforeNavigationEvent
