[satosa-users] SAMLFrontend versus SAMLVirtualCOFrontEnd

Hello SatoSa list! This is my first post as I am just getting started with SatoSa. Thanks to all for making it possible. I love it so far, the code and semantics are very clean! Question: It seems that I can configure SAMLFrontend and SAMLVirtualCoFrontend to both operate correctly in my topology ( 1 or many SP => 1 IdP. OR 1 SP=> many IdP ) as such I am uncertain of which module would be best to use. Can someone in the community tell me why I would want to use one module over the other? I think I must be missing some functional capabilities afforded by one but not the other. TIA -Jonathan +++
