Hi, I've tried to understand session management looking at http://hackage.haskell.org/package/clientsession and http://hackage.haskell.org/packages/archive/yesod/0.6.1.1/doc/html/Yesod-Han... I want a server to create a (unique) session-id, send it back to the client (how?) and handle requests from the client that supply this session-id somehow (how?). Thanks Christian P.S. "cabal install yesod-examples" finally failed with: Loading package ffi-1.0 ... linking ... done. Linking dist/build/form/form ... yesod/tutorial/mkToForm.hs:11:7: Could not find module `MkToForm': Use -v to see a list of the files searched for. cabal: Error: some packages failed to install: yesod-examples-0.6.0 failed during the building phase. The exception was: ExitFailure 1
