Problem with canonical url and session ids

[tdberlin]

Hi,

i have a problem with the following website: http://goo.gl/EuF4E

Google always indexes the site with session-id, although i use canonical url in this page.

Indexed sites: http://goo.gl/RQnaD Sometimes it goes right, but sometimes wrong.

Is it because we separate our session-id with ";" as separator? In the Google Webmaster Tools, i can´t choose jsessid as a parameter, so i think google does not recognize this. But if we have to change it (f.e. ? as separator) we have to spend many days in programming.

Any ideas? thanks for your help!

The rel canonical tag shouldn't remove the duplicate versions from the index. It would suggest to Google which version is the main version. If you want to remove the duplicate version from the index, maybe you could add a meta robots no index, follow tag.
