Webkit embedded browser disable cookies

I'm using this borwser in .net 3.5 winform application, on x86 platform.
http://sourceforge.net/projects/webkitdotnet/
The problem, when I logged in facebook, with this browser, and I've got the data from facebook, and I closed the form, and after I reloaded the form (every control recreated) the facebook logged again. So the session continued. I don't want this, I'would like to begin a new session. Can I disable the cookies of browser, or reset session, or something like this?
public WebBrowserTabPage currentPage;
WebBrowserTabPage page = new WebBrowserTabPage();
tabControl.TabPages.Add(page);
currentPage = page;
currentPage.browser.Navigate(Url);
currentPage.browser is a WebKitBrowser instance.

I've seen about my problem, and I found a variable (CookiesPolicy in WebkitBrowser class. I've set up this to disable cookies, and facebook didn't worked without cookies. I've tried to delete the WebkitBrowser's cookies from hard drive, but I didn't find them. After I've dicovered, there is a memory leak with Webkitbrowser. So I closed the from, but it didn't disposed, and stayed in memory. Finally I solved the problem, I've put the WebkitBrowser in another Project, and I'm running in different Application.
I'm using Inter Process Communication (IPM) for communicating between mother form application and the browser application
After the browsers
Application.Exit();
the session is disposed, and I can sign into facebook again.
Here is the sample code for IPM with named Pipe:

WebRequest class to post data to login form

I want to use the WebRequest class to post data to a website. This works fine, however the website I'm posting to requires cookies/sessions (it's a login form). After logging in I need to retrieve some account information (this is information on a specific page).
How can I make sure the login information is being stored? In AutoIT I did this using a hidden webbrowser, however I want to use a console application for it.
My current code (to login) is too long to post here, so it can be found here.

Take a look at my aspx sessions scraper on bitbucket. It does exactly what you are asking for, including some aspx webforms specific extensions, like sending postbacks etc.

You need to store the cookie that you get after logging in and then send that cookie when you request pages containing personal information.
Here is an example of using cookies with WebRequest
It is possible that you can't connect because the session has ended so in this case you need to relogin.

How do I redirect to a page after successful login?

I'm fairly new to web forms development, playing around with a project created using the ASP.NET Web Application template in VS 2010. After the user successfully logs in, I want the user redirected to a page I created. How do I modify my project to redirect the user after login? Any samples / tutorials / etc are greatly appreciated.
Thanks!

To simply redirect to a new page when your user has logged in, use the DestinationPageUrl property of your login control... assuming you're using the Login control that is.
If you need to do anything more advanced you can use the OnLoggedIn event handler for your Login control to perform a redirect manually, or add any code for event logging and such.
If you've rolled your own login control, and are just using things like text boxes and button controls, then in your Button_Click event, you can just use Response.Redirect("DestinationHere"); to take your users to a new page.

After you checked for login:
Response.Redirect("url");

I assume you're using ASP.NET Login control. There's a DestinationPageUrl property of that control that handles exactly that. If login was successfull user is redirected to URL provided in that property.

<asp:Login ID="Login1" runat="server" DestinationPageUrl="~/Admin/Default.aspx">
</asp:Login>
Go to Properties and Set DestinationPageUrl.

Server.Transfer( *url*) ?
(method on HttpServerUtility)
I know next to nothing about ASP.NET, but from my Java web developer daze, redirect is bad because it involves another network round trip to the browser and back when you really just want to continue processing in another page.
And Response.Redirect() really does issue a 302 response code ("try this other url instead") back to the browser. yuck. XP
Server.Transfer() looks like the java version of Response.Forward()

For Sharepoint farm solution development
Page.Response.Redirect("url");

The issue with Response.Redirect() is the 302. In some browsers (eg Chrome) this causes the new session cookie to be immediately invalidated.
In other words, using that method to redirect causes the user to no longer be logged in, so you did not accomplish your purpose!.

How to start new IE session with Watin

I need to know how to start a browser instance but with a new session. I tried to clear cookies and clear cache but this doesn't give me what I need.
In my case I add products to a basket, then close the browser, then use another url that adds different product, but always the old products are still in the basket.

for IE6-7 you should start a new browser session in a new process like this:
var ie = new IE("yoururl", true);
for IE8-9 you should set the no-merge option on the settings class before creating a new IE instance:
Settings.MakeNewIe8InstanceNoMerge = true;
var ie = new IE("yoururl");

Make sure that you're closing the browser properly (i.e. closing all its tabs and windows, including downloads and such) - look at the task manager to see if it's still running. Session might not be cookie-based (for example, it could be tracked in the same process that processes the request), and clearing browser cache isn't going to affect the open sessions in any way.
Assuming that you're developing an asp.net application or website you may try to right-click on the ASP.NET Development Server icon in the system tray and stop it, then re-run your project. That should kill all sessions.

We had the same problem here. IE re-uses the session over all its browser instances. If you want a new session just do:
Alt (menu) -> File -> New Session
Check this blog for more info.

Sessions are managed by cookies, you can clear all your cookies or just for the site concerned.
Try searching for IE Clearing cookies

IE 9 has one more way of not clearing all the cookies.
If you open the Dialog to Clear Cookies from the Options Menu in IE 9, you will notice that the first options says "Preserve Favorites Website Data." Leave this unchecked and you usual clear cookies, close browser should work.
Let me know if this helps, I think this should do the trick ;)

I will be trying this in WatiN soon, but just testing with my commandline switches, it looks like I can open multiple instances using
iexplore.exe -private -nomerge
and each instance will not interfere with the other ones.
This means it allows you to login with differnet logins on the same website, and they won't interfere with each other.
This needs further verificaiton, but so far it seems to work.
update: I found this old patch for WatiN that adds the privacy feature to the watin lib, it doesn't appear to currently be in the release- http://sourceforge.net/tracker/?func=detail&aid=3013950&group_id=167632&atid=843730

How to launch a browser and later direct it to a page?

I need to launch a browser, do some work and then make the browser navigate to a URL (in that order).
The first part is of course simple and I have a Process object. I am at a loss as to how to later direct it to the target page?
How do I treat the Process as a browser and make it navigate to the desired page?
Any help, pointers, code snippets appreciated.

Instead of launching the browser & then navigating to the page, just tell the OS that you want to run the URL. Windows will pick the correct browser, and navigate the user to the given URL.
System.Diagnostics.Process.Start("http://www.StackOverflow.com");

If you don't need to do this in production, you could use a testing library such as WatiN to do this:
using WatiN.Core;
//Placeholder page to launch initial browser
IE ie = new IE("http://www.google.com");
DoSomeWork();
//Now navigate to the page you want
ie.GoTo("http://stackoverflow.com");

My first instinct for this question was DDE, but it appears that has been decommissioned in Windows Vista so that is no good. Shame, as it was the only consistent mechanism in Windows for Interprocess Communication (IPC)...oh how I miss Arexx on the Amiga.
Anyhow, I believe the following will work but unfortunately, due to the way it works, it launches Internet Explorer irrespective of the configured browser.
If your application has a Form, then create a WebBrowser control on it. Set this to non-visible as we are only making use of its as a launching device rather than to display the web page.
In code, at the point where you want to show a web page, use the following code:
webBrowser1.DocumentText = "window.open('How to launch a browser and later direct it to a page?', 'BananasAreOhSoYummy');";
What this does is to tell the WebBrowser control, which is just the IE in disguise, to open a new window called 'BananasAreOhSoYummy'. Because we have given the window a name, we can use that line repeatedly, with different URLs, to change the page in that particular browser window. (A new window will be opened if the user has happened to close it.)
I will have a think about an approach that honours the user's default browser choice.

If you don't need the actual instance of IE, you can use the System.Windows.Forms.WebBrowser control.

I think instead of sending the browser a url you could send it javascript that would run and direct the browser to a site.
Not sure if this would work but I see no reason why it wouldn't
