Silverlight OData Services Sending Multiple Cookies

Question

I'm trying to pass multiple cookies to an OData service from a Silverlight application. I'm subclassing a DataServiceContext and wiring up to the SendingRequest event and doing the following:

        protected virtual void OnDataSourceSendingRequest(object sender, SendingRequestEventArgs e)
    {

        CookieContainer cookieContainer = new CookieContainer();
        foreach (var cookieContent in _cookies)
        {
            Cookie cookie = new Cookie(cookieContent.Key, cookieContent.Value.Value);

            cookieContainer.Add(new Uri("http://localhost", UriKind.Absolute), cookie);
        }

        var cookieHeader = cookieContainer.GetCookieHeader(new Uri("http://localhost", UriKind.Absolute));
        e.RequestHeaders["Cookie"] = cookieHeader;

}

If you look at the headers using Fiddler, only the first Cookie is propagated to the request. Is this a bug or am I doing something wrong?

Answer 1

I repro'd your issue and was able to fix it by getting the cookieHeader string to delimit the cookies with a comma instead of a semicolon, which is what the GetCookieHeader method seems to generate by default. 

I don't really know anything about this, but looking at http://msdn.microsoft.com/en-us/library/system.net.cookie.aspx, I think there are multiple specifications for how the header is written. Might have something to do with that.  I can investigate more if that would be helpful, but that might be enough to get you rolling again.

Ian,

Thanks for the reply. Interesting. I'll have a fiddle and see if comma-delimiting works for me. 

Answer 3

Any luck with the comma-delimiting?
