HELP, problems with sessions.....

hello, i have a problem with sessions..... on the host where i want to install the prog i developed on my laptop the sessions doesn't seem to work.... investigating on the laptop where the system works, i allready have some understanding problems with how sessions work..... i suppose that at the end of a session active page a session_encode is called and the result stored on the server side session file.... so i tryed session encode, at the end of my page i issue the result of that method and print out all session vars: session:user|s:6:"bboett";!|!groups| debug, after the run: num of sess vars:3 Sesvar 'user' = 'bboett' Sesvar 'bookid' = '2' Sesvar 'groups' = '2 3 4 1' i wonder..... i have 3 session vars, with values, but i cna't find them all in the encoded string..... and on the server that deosn't work, i see no values at all in the eoncoded string, so on the next call on another session aware page, not a single session var is transferred..... so what aren'T i understanding here? shouldn't all the vars and values be in the encoded string??? and what could cause the loss of the session vars on my server, what can i do to debug this? -- ciao bboett ============================================================== bboett@earthling.net http://inforezo.u-strasbg.fr/~bboett http://erm1.u-strasbg.fr/~bboett =============================================================== the total amount of intelligence on earth is constant. human population is growing....
