Hey John, Your best bet is to fiddler or charles your silverlight 3 app (sitting behind the proxy) to see what network traffic is going out and comming in (if at all).
My guess is the new SL3 networking stack and how it now does url resolution (between sl2 and sl3) may be the cause. BUT again just guessing. Fiddler should point you in the right direction. ________________________________________ From: [email protected] [[email protected]] On Behalf Of [email protected] [[email protected]] Sent: Tuesday, 1 December 2009 10:53 AM To: [email protected] Subject: ozsilverlight Digest, Vol 4, Issue 1 Send ozsilverlight mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit http://prdlxvm0001.codify.net/mailman/listinfo/ozsilverlight or, via email, send a message with subject or body 'help' to [email protected] You can reach the person managing the list at [email protected] When replying, please edit your Subject line so it is more specific than "Re: Contents of ozsilverlight digest..."

To: "'ozSilverlight'" <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset="us-ascii" Has anyone had this problem before? I have a Silverlight 2 application running fine, fully upgraded to Silverlight 3 and now from behind a proxy server all my WCF requests are getting 407 errors, the old Silverlight 2 site still work fine. The client is pretty sure their proxy is using AD to authenticate access to the internet and my application is using forms authentication to allow access to the asp.net page hosting the XAP and the service has this attribute: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] My guess is it's something with the new network stack in Silverlight3 and authentication but I'm not finding much info and can't replicate the environment from here. Hoping someone here has seen this before. John. -------------- next part -------------- An HTML attachment was scrubbed...

To: ozSilverlight <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset="windows-1252" Jon, For what I know by default it will use the browser's network stack unless you go out of browser or explicitly change to use the other one. However, what you're experiencing looks like symptoms of using the new stack. Check this post: http://developers.de/blogs/damir_dobric/archive/2009/08/22/soap-faults-and-new-network-stack-in-silverlight-3.aspx To enable it use this line of code: bool registerResult = WebRequest.RegisterPrefix("http://";, WebRequestCreator.ClientHttp); He explains the difference and the drawback, look at the last paragraph. Silverlight 3 provides the ?client HTTP stack? which, unlike the ?browser HTTP stack?, allows you to process SOAP-compliant fault messages. However, a potential problem of switching to the alternative HTTP stack is that information stored by the browser (such as authentication cookies) will no longer be available to Silverlight, and thus certain scenarios involving secure services might stop working, or require additional code to work. For more information, see HttpCookieContainerBindingElement<http://msdn.microsoft.com/en-us/library/system.servicemodel.channels.httpcookiecontainerbindingelement%28VS.95%29.aspx>. *I figured out that windows authentication which has been used in my services does not work anymore by using of new network stack. By default service proxies at the client do not send required authentication headers.* On Mon, Nov 30, 2009 at 4:39 PM, John OBrien <[email protected]>wrote: > Has anyone had this problem before? > > I have a Silverlight 2 application running fine, fully upgraded to > Silverlight 3 and now from behind a proxy server all my WCF requests are > getting 407 errors, the old Silverlight 2 site still work fine. > > > > The client is pretty sure their proxy is using AD to authenticate access to > the internet and my application is using forms authentication to allow > access to the asp.net page hosting the XAP and the service has this > attribute: > > [AspNetCompatibilityRequirements(RequirementsMode = > AspNetCompatibilityRequirementsMode.Allowed)] > > > > My guess is it?s something with the new network stack in Silverlight3 and > authentication but I?m not finding much info and can?t replicate the > environment from here. > > > > Hoping someone here has seen this before. > > John. > > _______________________________________________ > ozsilverlight mailing list > [email protected] > http://prdlxvm0001.codify.net/mailman/listinfo/ozsilverlight > > -- Miguel A.

On Monday, we released our new website which is written completely in silverlight. If you get a chance to look at the site (www.michaelhill.com) it has a number of interesting technical features that I would like to point out to you all. 1. Heavy integration of smooth streaming video. 2. Deep zoom for the product carousel. Significant bandwidth savings are made by the in-built lazy loading of deep zoom product images, plus the natural friction effect. 3. Integrated video inside a deep zoom image (company history section). 4. Search engine optimisation. 5. Deep linking : a. From search engine optimisation links b. Send to friend links c. Browser integration with forward/back buttons d. Sets the browser/tab title e. Appropriate link / title for adding to browser favourites. 6. Client side state. This reduces load on server such that when a user visits a page once, then navigates away / back, the application doesn't have to fetch data from the server. This is difficult to do in a traditional web application. 7. Custom install experience. 8. Analytics integration (via google analytics / javascript). 9. Isolated storage allows us to persist a 'super cookie' using serialized C# objects. 10. MVVM pattern. Dependency injection. 11. Application lifetime objects / client side services. 12. Animations / effects / scaling create smoother experience for user without unsightly page refreshes. 13. ADO.NET data services integration. Rest based / loosely coupled / dynamic data access. a. Easy to secure via policies rather than code. 14. Data driven application, where all menus / and content on particular screens can be changed via CMS. For example, the product carousels are all data driven. Dynamic loading of Xaml at runtime allows us to substitute in content / animations without rebuilding the application. You might have seen Ross Jempson post to the silverlight list occasionally. He is the owner and primary developer of the development company that implemented our site. We believe we have achieved a fantastic result and the capability of silverlight has helped us get there.

The way the menus disappear completely makes the site hard to use. I flipped windows whilst the site was loading (sorry short attention span) and when I came back the menus had already gone - took me a while to find them. - The site's infuriatingly slow - all the ui transitions are too slow for my liking. - There are some positioning issues whereby the close icon is half cut off by the edge of the screen - When you go into looking at one of the products (http://www.michaelhill.com/#ProductList?ProductMenuItemId=8&ProductMenuSubItemId=&ParentScreenId=3) it's then not clear where to go from there..... General feedback - visually it's quite pleasing. Navigation leaves quite a bit to be desired.
