Session in ASP.NET

Hi I have a small ASP.NET web application developed with VS 2005.
The web app runs on a MS Windows Server 2003 SE SP 2 and IIS v6.0.  

When two or more users are logged in at the same time, sometimes one user suddenly has the session for another user. And they can be on the same network or on different networks, also sometimes in different contries.
The website can be accessed through an external domain and an internal domain.
Can anyone help me figure out what this could be and/or help me fix this problem?

Thank you!

/Erik

do you call your session Id form a function defined as static ?

no object instances are created with static (or shared in vb) calls. this can cause your issue.

you can remove the static definition and create an object from your classes in your website.

call only constant values from static functions (i.e: a value from your web.config file)

No I am not using static functions or variables. The session variables is mainly used in the master page. And in some user controls to check access to that page. So the session variables are mainly called in Page_Load.

Thanks for the replies, I have been busy lately and have not been checking you're answers. Sorry!

No there is no public variables only public methods. There might be some protected variables.

I found some redirects that used absolute paths. I changed them to relative paths. And I have not got a report that they have had any issues with the sessions since then. Could this have been the problem maybe?
