Apache configuration

Hi, I am having problems in trying to configure Apache on my PC correctly. FYI I am using Win95 and PHP4. I have configured Apache so that it will run PHP scripts, however when I try to start a session I get the following messages: --- Warning: open(/tmp\sess_20e483a01d217181f5379858afee4cf4, O_RDWR) failed: m (2) in d:\apache\htdocs\session.php on line 2 Warning: open(/tmp\sess_20e483a01d217181f5379858afee4cf4, O_RDWR) failed: m (2) in Unknown on line 0 Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0 ---- I can see that the script cannot locate the '/tmp' directory. What my question is where does this '/tmp' directory need to be created and do I need to update the 'httpd.conf' file accordingly, and if so where within it? Many thanks Alexis
