sessions via mm?

Howdy, I'm playing with sessions in php4 to see how stable they are, and am trying to get sessions via mm working, but I can't seem to get it to work, but I'm not getting errors. I have set my php.ini to [Session] session.save_handler = mm ; handler used to store/retrieve data session.save_path = /tmp ; argument passed to save_handler ; in the case of files, this is the ; path where data files are stored session.use_cookies = 1 ; whether to use cookies session.name = PHPSESSID ; name of the session ; is used as cookie name session.auto_start = 0 ; initialize session on request startup session.cookie_lifetime = 0 ; lifetime in seconds of cookie ; or if 0, until browser is restarted session.cookie_path = / ; the path the cookie is valid for session.cookie_domain = ; the domain the cookie is valid for session.serialize_handler = wddx ; handler used to serialize data ; php is the standard serializer of PHP session.gc_probability = 1 ; percentual probability that the ; 'garbage collection' process is started ; on every session initialization session.gc_maxlifetime = 1440 ; after this number of seconds, stored ; data will be seen as 'garbage' and ; cleaned up by the gc process session.referer_check = ; check HTTP Referer to invalidate ; externally stored URLs containing ids session.entropy_length = 0 ; how many bytes to read from the file ; session.entropy_file = ; specified here to create the session id ; session.entropy_length = 16 session.entropy_file = /dev/urandom session.cache_limiter = nocache ; set to {nocache,private,public} to ; determine HTTP caching aspects session.cache_expire = 180 ; document expires after n minutes my config is ./configure \ --with-mysql \ --with-oci8=$ORACLE_HOME \ --with-apache=$RC_PROJ_ROOT/apache_1.3.12 \ --with-ftp \ --with-gd \ --enable-xml \ --enable-wddx \ --enable-sysvshm \ --enable-sysvsem \ --enable-inline-optimization \ --with-zlib \ --enable-track-vars \ --enable-magic-quotes \ --disable-debug Is there something that I'm missing? My simple test.php scrip looks like <? session_start(); if (!isset($ass)) { session_register("ass"); $ass = 0; } else $ass++; ?> <html> <? echo "ass = $ass<br>\n"; ?> </html> the output is always ass = 0; I have cookies turned on, and I'm not getting a session cookie using mm. If I switch to save_handler = files it works fine. I've tried with the wddx and php serialize_handler to no avail with the mm modules. this is running on a linux box with apache 1.3.12 on Mandrake 7.0 Thanks for the help Walt
