On Sat, Mar 19, 2011 at 10:06 AM, Florin Jurcovici florin.jurcov...@gmail.com wrote: Hi. Just for comparison: PHP does not provide sessions in the same way a servlet-based platform provides. PHP actually destroys the in-mem representation of sessions after each request is served, whereas a servlet-based platform caches the sessions in mem between requests. ASP.Net also serializes session state, but not into a cookie - it uses a hidden field instead. Which works around cookie size limitation. You don't even have a choice of database sessions with ASP.Net. OTOH, even if performance might suffer, scalability, as far as the sessions mechanism is concerned, is excellent - you don't need session replication. Servlet-based platforms provide the most complicated solution, when compared to the other two. They keep sessions in mem, which improves performance (no serialization/deserialization for each request), but creates potential scalability problems. You won't hit the wall at a few thousands of users, but replicating maybe a million sessions among no more than a hundred servers causes the replication process to consume quite a lot of resources, the resources being used for replication increasing faster than linearly with each added server (not quite exponentially, though). You can use sticky sessions with most servlet-based platforms, but these come with their own problems (already described by a previous poster). Nevertheless, in mem sessions a la servlets are a very convenient mechanism to use - the session replication is provided by the platform, and the app programmer doesn't have to worry about it. All three approaches rely on every piece of data in the session being serializable, so you can't store interesting objects, like an open file or the like, in sessions. Does anybody know of any fundamentally different session sharing/replication mechanism? br, flj -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- Signed, Alessandro Ferrucci ---End Message--- ---BeginMessage--- Hello *, since I have re-installed mail.tamay-dogan.net with Debian/Squeeze on a new machine, my /srv/log/apache/error.log ist arround 450 times bigger then the access.log du to following (and similar) entries [ '/srv/log/apache/error.log' ]- [Thu Mar 17 00:14:16 2011] [error] [client 89.204.153.240] PHP Notice: Use of undefined constant DIR_BASE - assumed 'DIR_BASE' in /srv/htdocs/index.php on line 3 [Thu Mar 17 00:14:16 2011] [error] [client 89.204.153.240] PHP Notice: Use of undefined constant DIR_TOOL - assumed 'DIR_TOOL' in /srv/htdocs/index.php on line 5 [Thu Mar 17 00:14:16 2011] [error] [client 89.204.153.240] PHP Notice: Use of undefined constant DEF_DIR_TOOL - assumed 'DEF_DIR_TOOL' in /srv/tdphp-vserver/includes/00_main.inc on line 42 [Thu Mar 17 00:14:16 2011] [error] [client 89.204.153.240] PHP Notice: Use of undefined constant DEF_DIR_BASE - assumed 'DEF_DIR_BASE' in /srv/tdphp-vserver/includes/00_main.inc on line 65 [Thu Mar 17 00:14:16 2011] [error] [client 89.204.153.240] PHP Notice: Use of undefined constant DIR_HOST - assumed 'DIR_HOST' in /srv/tdphp-vserver/includes/00_main.inc on line 88 [Thu Mar 17 00:14:16 2011] [error] [client 89.204.153.240] PHP Notice: Use of undefined constant SCRIPT_FILENAME - assumed 'SCRIPT_FILENAME' in /srv/tdphp-vserver/includes/00_main.inc on line 88 snip [ '/srv/htdocs/index.php' ]- ?php define(DIR_BASE, /srv); define(DIR_TOOL, /srv/tdphp-vserver); include DIR_TOOL . /includes/00_main.inc; ?

The first parameter of the define function should be a string.
Whats the name of the error loging setting which produce this and WHY are

It would appear that your new server has defaulted to logging PHP notices. You
can turn this off in your php.ini, or better yet fix the issues that are
causing them. In my experience notices can often indicate more serious
potential bugs.
I have switched off anything but it continue to create more then 46 GByte
error files (18) per day.

Have a look at what $_SERVER['HTTP_ACCEPT_LANGUAGE'] is set to because it's
clearly not in the format this code is expecting.
