KIO / KWebView and PrivateBrowsing (Cookies)

[Alex Fiestas]

After reading the patch and understanding a little bit more how this work I 
reached the following conclusion (potentially wrong as before :p).

storageDisabled should work as it does right now (without the patch), it does 
disable any storage and allow reading, which imho it is exactly what you 
expect from "disable storage".

So, how do we enable Private Browsing in AcessManager?
By setting a different CookieJar, the default Qt implementation will do the 
job perfectly storing all the cookies in memory until the jar is destroyed 
(Private Browsing disabled).

Right now any new CookieJar set via QNetworkAccessManager::setCookieJar will 
be ignored by Integration::AccessManager since at the end kio_http will use 
the "auto" cookie mode.

So, the solution should be:

-Fix the support for external QNetworkCookieJar's, this will have to be done 
anyway since Integration should have support for it.

-Fix KWebPage to set a custom CookieJar when private browsing is activated.

What do you think? does it make any sense at all this time?

Thanks !
