Awesomium, change useragent and referrer

问题

I just started to use awesomium. I wanted to understand how to change user-agent and referrer. i need for example to initialize 5 istance o awesomium webcontrol and for each of them i need different user-agent and different referrer. this is my simple code

        private void newbrowser()
    {
            browser = new Awesomium.Windows.Forms.WebControl();
            browser.Paint += browser_Paint;
            browser.Location = new System.Drawing.Point(1, 1);
            browser.Name = "webControl";
            browser.Size = new System.Drawing.Size(1024, 768);
            browser.Source = new System.Uri("https://www.google.com/", System.UriKind.Absolute);
            browser.TabIndex = 0;

    }

    void browser_Paint(object sender, PaintEventArgs e)
    {
        browser.Paint -= browser_Paint;

        System.Collections.Specialized.NameValueCollection myCol =
            new System.Collections.Specialized.NameValueCollection();
        myCol.Add("Referer", "http://www.yahoo.com");

        browser.SetHeaderDefinition("MyHeader", myCol);
        browser.AddHeaderRewriteRule("http://*", "MyHeader");
    }
    private void button1_Click(object sender, EventArgs e)
    {
        newbrowser();
    }

these 2 lines give an error

        browser.SetHeaderDefinition("MyHeader", myCol);
        browser.AddHeaderRewriteRule("http://*", "MyHeader");

Error 1 'Awesomium.Windows.Forms.WebControl' does not contain a definition for 'SetHeaderDefinition' Error 1 'Awesomium.Windows.Forms.WebControl' does not contain a definition for 'AddHeaderRewriteRule'

thanks for the help

You need to set the user agent of the WebCore that governs your WebControl. This must be done before you create your WebControl.

public WebForm()
{
    if ( !WebCore.IsRunning )
        WebCore.Initialize( new WebConfig() { UserAgent = "YourUserAgent" } );

    InitializeComponent();
}

My solution - is wrapper around WebBrowser, that implements IResourceInterceptor and can navigate with any additional headers:

public class class BrowserWrapper : IResourceInterceptor
{
    public BrowserWrapper()
    {
        WebCore.ResourceInterceptor = this;
        //BrowserWrapper can contains WebBrowser or knows how to delegate him Naviagtion (Source property)
    }

    private readonly ConcurrentDictionary<Uri, string> headers = new ConcurrentDictionary<Uri, string>();

    public void Navigate(Uri uri, string additionalHeaders = null)
    {
        if (additionalHeaders != null) headers.AddOrUpdate(uri, additionalHeaders, (url, h) => h);
        //Navigation to browser (WebControl.Source = uri...)
    }

    ResourceResponse IResourceInterceptor.OnRequest(ResourceRequest request)
    {
        string h;
        if (headers.TryRemove(request.Url, out h))
        {
            var hs = h.Split(':');
            request.AppendExtraHeader(hs[0], hs[1]);
        }
        return null;
    }

    bool IResourceInterceptor.OnFilterNavigation(NavigationRequest request)
    {
        return false;
    }
}
