RSS login and Share login failed

[fast3r]

Hi, I'm using Alfresco 3.0 Labs with Share.
I have a weird, serious problem with RSS Atom Feeds for Site activities that I'm unable to solve.

RSS Feed are pw protected through unsecure login. When a user tries to access the feed while he isn't logged into Share, Tomcat creates a JSESSIONID cookie.
When the user tries to login again to Share, probably the Alfresco auth system fails to recognise the server session and throws an exception about authentication.
It is impossible to login until cookies are not manually deleted or the session expires.

How can I fix this? I know external feed readers should be used instead of browser's reader, but I can't force my users to not open the rss file while it is linked in Share dashlets.
Is it possible to force the RSS Feed auth system to create a different session, maybe with a cookie with different path to avoid these problems?

Thank you for any suggestion!

No one can help me?

I found out that there is a problem with the tomcat session when I try to re-login into Share after opening the feed with basic http authentication while logged out.
I get a HTTP 500 Internal Server Error each time I try to open the login page, until I delete the cookie JSESSIONID created by the rss feed script.

How can I fix that?
Or, basically as a workaround, how can I just delete the JSESSIONID cookie before the login page loads?

Thank you VERY much!
