<gapos> wrote in message news:195548@test.componentone.com...I am experiencing the following problem when I try to use session cache stored in file. When the session cache is stored in memory everything works fine when I click on the button to generate a post back and reload the page. When I change the setting and store the session cache to disk I get an empty page when the button is pressed. I am attaching a sample project to illustrate the problem. Any help is highly appreciated Best Regards George http://home.componentone.com/cs/forums/195548/ShowPost.aspx
