SSO between Web UI and SAP CE server

Hi Experts,

I have a requirement where in, from SAP Web UI, one hyperlink should call url running in CE server. SAP Webui runs in browser and generates MySAPSSO2 cookie. Requirement is from SAP web Ui - to - Portal (not vice versa).

Do any one know how to do SSO for such type, so as to authenticate portal based on cookie created by SAP Web ui.

Thanks and regards,
