Hi
I have read all kinds of help documentation on this subject but can't seem to find the best fit, or get any to work. I have written the javascript app below. The layer being used is secured as I would not want the contents being made available to everyone, except for people who are using the app. They will have already logged in to get this far so I just need the application to handle the logging in to get the map data back. (ie at the moment it asks for an ArcGIS server log in). I can find lots of information about accessing secure applications, but not specific layers within a javascript app...any help would be great.
