Dear All, I am not sure if this is linked with my previous posting (Interleaving requests) but unpredictably - that is, I cannot reliably reproduce it - I get a message along the lines of: "Your session is invalid or has expired. Please reload this page to start a new session. Expired or invalid session: 3c2b77d527b61517" This occurs in any make of browser across 3 operating systems. If I reload the page...it carries on with the same session ID. I was alerted to this becuase reloading should cause a new login (if the session has expired and a new cookie is issued, the user value should be blank) plus, if I force an error or examine the cookie within the browser, the cookie ID is the same. Is the cookie error message being displayed in error (!) by quixote because it is misrepresenting some other error, perhaps? -- Robert Ladyman Tel: +44 (0) 7732 771 649 http://www.file-away.co.uk Sent to you via the Magach Wireless Network http://www.file-away.co.uk/rlan.htm
