I'm using this borwser in .net 3.5 winform application, on x86 platform.

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:

I have a small application that logins into a website and performs some actions. I need a method to clear the cookies and essentially "Force" logout of the website so I can perform the actions again. The easiest way is to just clear the cookies and then repeat the login process, but I haven't been able to figure out how. I have found this resource from Microsoft but I haven't been able to locate any sample code
https://learn.microsoft.com/en-us/dotnet/api/microsoft.web.webview2.core.corewebview2cookiemanager.deleteallcookies?view=webview2-dotnet-1.0.1462.37
I believe WebView2 and Edge are closely related and also want to make sure by doing this I do not end up clearing the cookies on their main browser if they use Edge
Any assistance is greatly appreciated
If you have a WebView2 class you can do the following to clear cookies and reload the page:
// Clear cookies for this WebView2 and all WebView2s
// sharing the same user data folder.
webview2.CoreWebView2.CookieManager.DeleteAllCookies();
// Reload the document after clearing cookies
webview2.CoreWebView2.Reload();
The above code must be run after the WebView2 has finished initializing its CoreWebView2.
When you create a CoreWebView2 it belongs to a user data folder and browser process. Changing cookies via the CookieManager applies to all CoreWebView2s sharing the same profile and that user data folder.
You cannot share state between the WebView2 and the browser so you will not be modifying cookies in the browser.
How about using Private mode?

You can clear cookies only dispose instance.
Using DotNetBrowser in WPF app in Windows 10. When navigating to certain pages that typically save user data and use it in subsequent loads to restore your settings, it doesn't seem to be happening.
See example code here of a very simple implementation. If I use it to browse to Amazon's site and login, after closing and reopening app, I'll need to login again -- in a normal browser like Chrome, it retains my login. Is something missing in the code to enable this similar behavior?
To make it work, I had to set UserDataDirectory when creating engine:
engine = EngineFactory.Create(new EngineOptions.Builder
{
RenderingMode = RenderingMode.HardwareAccelerated,
UserDataDirectory = $"{Environment.ExpandEnvironmentVariables("%AppData%\\MyApp\\Chromium\\User Data")}",
LicenseKey = ConfigurationManager.AppSettings["DotNetBrowserLicenseKey"],
}
.Build());
I have this weird problem my website won't cache the mainsite!
Here is a little overview about what I am trying to do
The first page that is being loaded is the
[DidTheUserLoggedInBefore?.html]
which checks if the user already has logged in or not depending on that result the user will be redirected to
either [LOGIN.html] or [MAINPAGE.HTML]
pretty simple!
But here comes the problem when the user restarts the app in Offline mode the App should redirect immediately to the mainpage (assuming the previous login was a success).
But that doesnt happen at all.
Instead the [DidTheUserLoggedInBefore?.html] from cache was called (which is correct) and starts loading the mainpage which isnt in cache which results in a whitescreen aka my error.
So how do I get my App to cache the Mainpage?
I've tried setting CacheSize to 100, but that didn't changed a thing :(
You can't check if the user has logged in with a .html file... You need some sort of server side language to set a cookie... Anyway this isn't much clear, is your "app" just a webview?
I couldn't let the webview cache more than 2 (simple) webpages...
WebView ignores he offline.manifest.php file too ...
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
Is it possible, using the gecko / firefox XPCOM interfaces, to delete or invalidate a user's active session without closing the browser? I am using Gecko embedded (specifically GeckoFX) in an application where it is possible that multiple users might use the browser component across the lifetime of the application.
The application packages web browsing with various other functionality, and when the web browser is 'closed', the app remains open. It seems that as far as the gecko engine is concerned, as the process hasn't closed, the active session is still active. If a user is to log into Gmail or Facebook, for instance, and then close the browser, upon reopening the browser and navigating back to one of those pages, that user is determined to still be logged in. As multiple users can use the application without the application actually exiting, this raises privacy issues.
I have tried calling NS_InitXPCOM2 and NS_ShutdownXPCOM within the constructor / dispose method of the browser control, however NS_InitXPCOM2 cannot be called after NS_ShutdownXPCOM within the lifetime of the process, so this simply crashes.
I have also used the PurgeHistory method of nsISHistory and the evictEntries method of nsICacheService - none of these appear to have an immediate effect within the life of the process.
Does anyone know of any XPCOM interfaces that can achieve this? Alternatively, any pointers in direction of similar functionality, be it through XPCOM interfaces or Firefox extensions would be greatly appreciated (are there any extensions that allow you to clear your current browsing session without reopening the browser? or that provide you a different session between each Firefox window / tab?)
The program is written in C#, however answers in any language are appreciated.
Many thanks
I finally found the interface that seems to allow this: nsICookieManager removeAll()
Relevant C# interfaces / code for those using GeckoFX:
[Guid("AAAB6710-0F2C-11d5-A53B-0010A401EB10"),
ComImport,
InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface nsICookieManager
{
void removeAll();
void remove(string aDomain, string aName, string aPath, bool aBlocked);
}
and Xpcom.GetService<nsICookieManager>("#mozilla.org/cookiemanager;1").removeAll(); in appropriate location.
