Invalid session/cache displayed

I am have a webserver and it is providing cross session content ( same URL but different web applications within the URL) sporadically

Details: Windows 2008 R2, IIS7, Behind Load Balancer that hosts the SSL

The user logs in, the request appears with an HTML 302 status that has the correct URL listed but above this message there is invalid session content (like from other web page submissions but from different web application entirely).

Where is the redirect happening or how do I resolve where this redirect comes into play?  In IIS there are no site redirects applied, also this does not happen each time a request is made but periodically.

If you look at the error message, the 302 is telling you that the content has HTTP Cache Controls enabled as "Private" meaning that the content can only be cached by the client making the http request.

I would recommend that you check the browser settings for the client(s) having the issue.  I would adjust the size of their local browser cache to be much smaller... in the realm of 200-250MB.

If you have control of the other web application, I would investigate why the Cache-Control headers are configured in this manner and see if you can change the setting to a more optimized setting.

Adding an time expiration to the header would also help solve the issue.
