Presto in single sign on environments/accessing and passing cookies.

Hi,

I work at a company that uses the CA SiteMinder product to protect our internal web content. We are interested in using Presto internally, e.g. to fetch internal web content, transform it in a mashup, and serve up the transformed content (e.g. as an Atom feed or in Mashlets). However, can Presto be made to work in a SiteMinder protected environment? In particular, all web content protected by SiteMinder will require SiteMinder-specific authentication credentials to be passed as HTTP cookies in order to gain access to the content. So could Presto be configured to get these cookies from the browser (note that the cookies are initially set by redirecting the user to an https login screen where the user provides username and password, after which the user is redirected back to the original desired url) and pass these cookies in its http requests to fetch our internal SiteMinder protected content? In general, is there any documentation for getting Presto to work in such single sign on environments, or in general how Presto can access browser cookies and pass them on in subsequent http requests?

thanks,
Andrew Smith
