Why don't you try to disable you auto-prepend file using .htaccess? Or aren't you using Apache?

Hi, well, yeah, there is that option as well, I have root access.
But, I was just wondering - why is this the way it is?
And auto session start can sometimes come in handy, so I would like to keep it if possible.

Thanks for the report. Feel free to open a pull request, otherwise we won't fix this ourselves.

Hi mattab,

I looked into the source code of Piwik, and for one, I could not locate where the hack it starts the session?

It does not use session_start() method, for sure. I have located Session class and traced the code from there, but it does not work:

if(!isset($_SESSION)) { $startedCleanly = session_start(); } else { $startedCleanly = true; }

Also, I see that Piwik 'likes' to store it's session files to local folders, instead of general one (defined in php.ini).

Now, I do not understand why is your attitude towards this issue so strict, because, sessions are shared resources in PHP, it is not something that can be taken for granted. If any app could start it's own session (by unique ID), we would not have such a problem. But, that is not the case, so, a reasonable and responsible use should be conducted IMHO.

Thanks,
Regards

P.S.
I have tried the alternative method with database storage, but for some reason, it did not work.
I have edited config file and added the line per instructions under [General] section, both:

session_save_handler = dbtable

and

session_save_handler = "dbtable"

Do we have to create new table @ piwik's database with particular name and replace generic "dbtable" from above? Because, above line just does not work at all.
