Sessionproblem !?

Hello, I´m working on a little web shop solution for a school project with php, adodb, a MS Access Db and an apache server. Therefore I have some questions and hope someone have an idea or can give me a hint. I decided to choose sessions for the data storage because I heard or read somewhere that this is better than cookies - is this so ? My problem is that when I start a php site the loading bar of the site never finishes - the site appears and works but never stop loading !? Has anyone an idea what the reasons can be for this. -- Thanks in advance for your help, regards Marcos GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net
