using proxy.ashx in silverlight

Hi,

I'm trying to use the silverlight proxy.ashx and proxy.config provided by esri to use secure services (http://help.arcgis.com/en/webapi/silverlight/help/SLProxyPage.zip) with out any success.

The proxy.ashx and config are located in the root directery of the application folder and I can call the proxy page eg https://<servername>/app/proxy.ashx?ping for which I get the "Hello proxy" webpage return.

I can't call any of the services listed in the conifg file eg https://<servername>/arcgis/proxy.ashx?https://<servername>/arcgis/rest/services/ or http://www.bing.com/

I get HTTP 500 Internal Error.

When I reference the ProxyUrl="../proxy.ashx" for the service in silverlight I get the following errors from the initialisation failure (attached).

Any help is appreciated.

Regards,
Elliott

Thanks for the reply Jennifer,

I have reviewed this web page before, this is the page that I accesssed the proxy files from. However it does not provide me with a solution to the problem that is occuring.

Any additional help would be greatly appreciated.

The steps defined here are similar to what you need to do to set up your proxy pagehttp://help.arcgis.com/en/webapps/silverlightviewer/help/index.html#//01770000001s000000. You need to edit proxy.config to include your service url.

Thanks again for your reply Jennifer,

I've gone through the steps outlined in the second web link you've supplied. Unfortunately this also did not produce a favourable outcome.

For example I've generate a token placed it in the silverlight app to make sure it works. Then I've alter the silverlight app pointing to the new proxy page, put the token in the config file and referencing the service, but I get the error below. Even if the service is completely open I still receive the same error.
