Session variables for classic ASP running on IIS7

Seems that lot of people already know that issue but I can not find solution.

We transferred our web app from IIS6 to IIS7. For authentication purposes and some other functions we using session variables. While on IIS6 we did not had any problem but now all users losing their time and patience because app variables are being lost somewhere between pages being submitted and as a result users get kicked out of the app.

• Server is 2008 R2 with 64 bit OS.
• Default installatio开发者_JS百科n by Dell so it should be running on 64 bit mode.
• We do not have any third party elements or modules. All developed in-house.
• Database obviously MS SQL 2008 as well, on the same server (I know it is bad but we limited in resources and money).

So does anyone know what is going on and how to fix this?

Resolution of that problem is simple: do not use any other port except 80. As soon as I moved site to separate IP with port 80 (use of header on the same IP was not tested) -- all problem gone....

Have you deployed your application as a new website or a virtual directory on the IIS ? Remember that for the methods in the global.asa to be executed by the server you need to deploy your application as a new website not just a virtual directory under an existing web site.

I think the best way is to add logging code to trace when exactly a session variable is lost; after a post back to the server, redirection, etc... to try to narrow down the causes. good luck.

Look here for a solution...
