(not to be confused with 'tossing my cookies')

I need to include what this company calls a 'widget' ... is really off-site javascript... which doesn't use flash.  My idea is to use the IFrame module to insert an .aspx page that will set the user_ID cookie, initiate their 'proxy.aspx' to negotiate the delivery of the correct javascript.

My problem is,  the cookie that I create in my page (which I have located in DNNRoot /portals/_default/subDIrectory) is getting lost in the exchange.  Watching the exchange in firebug,  I can see that I get an 'oAuthToken' and 'oAuthSecret' value from the external site, but then the cookie name is not passed and the authentication fails.  I tried to set the cookie  domain value (www.mydomain.com/portals/_default/subDirectory/).. but it resulted in not storing a cookie at all.  My thinking was, I should be able to specify my subdirectory as the domain, to ensure that the cookie I sent would be used by the proxy page.

Note:   I can successfully navigate to my page (which will be imbedded in the iFrame) directly (without logging in)...  with the results described above.  Once I get the page working on its own,  then I'll try it from the DNN iFrame.

external .js files successfully load,  I can successfully create the cookie (if I don't specify domain), and other JS routines are working fine... so I've excluded that code.   The external 'widget' is called via javascript with the following code snippet:

if (jQuery.cookie("companyProduct_user_id") != null) {


             companyProduct.Api.isAuthenticated(function(success, fail) {
                 if (!fail) {
                     loadWidget();
                 }
                 else {
                     renderLoginButton();
                 }

             });


         }
         else {
             You must set your user Id.");

         }


function loadWidget() {

             CompanyProduct.Api.loadAPIWidget('myrequests', 'content', { frame: true, width: 600, autoHeight: true }, {}, false);
         }




I would like to host 'self-supported' pages such as this within the DNN framework (in addition to building web control modules) and use the framework, but don't fully understand the implications of the DNN web.config.
I am beginning to transfer SOAP and REST web services  into this DNN instance, so I would appreciate tips on where web references should be placed, and how to incorporate these 'interface methods' into DNN.

Thanks in advance
