Hello, I am having problems using Application.GetCookie() within a browser-deployed XBAP application. I know the browser that is hosting the XBAP application has cookies (including the ASP.NET session cookie). When I get the XBAP application to call Application.GetCookie, it throws the following exception: No more data is available (Native Error Code=259). I notice that if I call SetCookie(), then GetCookie() retrieves a value. That said, the important part is to get the browser's session cookie so that the XBAP application can interact with the host website. Does anyone know how to get the cookies from the host browser of an XBAP application? Thanks, Shan McArthur |

Thanks for the reply, but that solution will not work. The XBAP application does not integrate with browser session cookies at all, nor will it work in websites that use https cookies that are not written to the hard drive. Using this suggestion, if the browser cookie changes, the XBAP application would be unable to detect it and would be using old values. In addition, it would require an insecure web service to pass values from the browser to the XBAP and the application would be very sensitive to communication issues. I have seen the website example of communicating between an XBAP application and a browser through a web service, but the application breaks frequently - there is no way that form of communication is qualified for enterprise development. Unfortunately, this completely cripples a developer from integrating an XBAP application into a browser-based application. Cookies have been part of the HTTP specification from the start and are required to build session-based web applications. It is very unfortunate that Microsoft did not consider the needs of developers using the technology before they rushed this out the door. As a minimum, integration with the browser session cookies as well as rudimentary communication with the hosting window (equivelent of window.opener or window.frame.top) is an absolute requirement, and without these two basic capabilities, XBAP will be unsuitable for web development.
