WCS page with html form - need to send data to third party(external system) - can this be done with

Hi,

we have a requirement where html form (jsp page) that should capture data and send it to external (third party) system. (not to WCS db).

Note: along with content management capability, we have some pages, that captures data for external system. Key point is that, the pages needs authentication/authorization that rest of the pages use. So, we do not want to use separate web application. we wanted to use it similar to other pages of the site created in webcenter sites. Is it possilbe to host these pages in separate application and still use CAS authentication/authorization? Please let me know.
