Hi,

I have used DNN 4.4.8 Version to  create multiple portals in DNN and used Iframe to load Third Party Site URL in Our DNN Module.Once the third party url was loaded the session got expired in DNN Portal.

We have created one client server Application.We have created Httphandler Method in Server Application to Process the Client Request and to Check whether the User has rights to access to the Server application.We have used the Httpcontext.Request.Params Method in the Server Application to get the Input value from the Client Application to process the client request and to response back to the client.
We have created multiple Websites in a single Instance. If we run the Client Application from the Main application(root site)it is working fine. No Issues.

We have passed the Guid to the server application and read the Guid values in Httpcontext.Request.Params[Guid] its return as Null Value. We have check the value is null and raise the custom Exception like “Invalid Guid”.

The problem occurs in Sub Portal only.

I have used the SQL Server Authentication mode in DNN Portals. So Could you please help me out on solving this issue.

Regards,
Mani
