Secured service with https

[DeminHu]

In ArcGIS Server 10.1, when I use a secured service, in .xaml file, I do the following like:

<esri:ArcGISDynamicMapServiceLayer ID="TestLayer", Url="http://mydomain/arcgis/rest/services/TestSv/MapServer" Token="XXXmnbgh-456xxxxxxx" />
It works fine.


But recently I set up  ArcGIS Server system with Reverse Proxy server, set the Urls as https.
When I use the following:
<esri:ArcGISDynamicMapServiceLayer ID="TestLayer", Url="https://proxydomain/arcgis/rest/services/TestSv/MapServer" Token="XXXmnbvhk-476xxxxxxx" />
Even the token is valid, but it doesn't work.

I tried SignInDialog sample with https, it didn't work either ( I already applied SP1 and security patch).

any help ?

Thanks.

The problem seems solved, I made a silly mistaken.

The page  with https map serivices should be opened with HTTPS, not http.
