Session Variables Randomly Lost between Pages

[leesiulung]

My web page uses a session to keep track of who logged in. What I noticed is that the session variables stored appears and disappears randomly on different pages. The wierd thing is that my code is very simple.

For the life of me I can not figure this out....

Add addtoken="yes" to the cflocation tag.

Are your servers loadbalanced by any chance? If so, make sure it's done properly with sticky sessions otherwise the user may be thrown from one server to another.

Hope this helps.

Do besides what Hlevin says

clientmanag ement="yes"
setClientCookies="yes"
sessiontimeout=#CreateTimeSpan(0, 2,0,0)#
<cfdum p var="#Session#">

I go through a hosting company and do not expect them to do any load balancing.

What are sticky sessions?

The cflocation tag also has the addtoken="yes" to it now and symptoms persist.

I tested the case with sessiontimeout=#CreateTimeSpan(0,2,0,0)# instead of the sessiontimeout=#CreateTimeSpan(0,0,120,0)# and symptoms still persist.

Any other suggestions? I think I ran into a wall here....

which version of CF does your hosting company have exactly (please include Updater and hot fix level)?

can you confirm with your hosting company that the CF server is not part of a cluster?

can you post any and all code in the application that involves session variables? (or send it to me privately aqlong _at_ gmail.com if you'd prefer)
