indeed,
i forgot to mention that the problem was in the documentation, not in the code

good question, as i'm having troubles here :
in a small program, i'm using webkit to load a php page which is served on localhost,
so i call webkit_web_view_load_uri function.
i want to populate the http headers with a Cookie: field
so that the php page gets the cookie.
The only object i found exposed by webkit was SoupSession (webkit_get_default_session).
The following code hangs, and i don't get why. I'm new to gtk and stuff.
What's weird is that it does not hang if i set domain != "localhost"
But in that case the php page won't get the cookie, so it's useless.


SoupSession* fSession = webkit_get_default_session();
SoupCookieJar* fCookieJar = soup_cookie_jar_new();
soup_session_add_feature(fSession, SOUP_SESSION_FEATURE(fCookieJar));
SoupCookie* fCookie = soup_cookie_new(cookiename, cookievalue, "localhost", "/", 1);
soup_cookie_jar_add_cookie(fCookieJar, fCookie);

(then, i call
webkit_web_view_load_uri(webview, gURL);
gtk_main();)

i know i'm probably wrong doing this, but i'm a bit short of examples.  

Jérémy.
