Hallo, when a registered user surfs on the website he will be kicked of after some time or specific action automatically. I use forms authentication. I tried to debug it but I could not find the reason. I've recognized that this problem exist only with firefox browser not on IE - did someone have an idea what can cause the problem? Regards, Guimel
...If you search you'll find ASP.NET and FF don't mix as well as might be expected. One of the reasons is FF does not handle Forms Authentication the same way IE does. FF also does not like HTML encoding where it is expecting CSS. Even if it's right. Something that does cause this in FF is the way ASP.NET uses Themes for Forms. FF will direct back but miss the settings, such as: Timeout. Take a look at this, I hope it helps but if not you're closer to a solution: http://stevedunns.blogspot.com/2006/10/forms-authentication-and-stylesheet.html
