The user has indicated that the application seems to be kicking her out, even
though she is sure that she is submitting a form faster than every 30
minutes. I thought that I had set the Web.Config on the ASP.NET application
to time out after 30 minutes of inactivity, but maybe I don't have something
set up correctly. Here's the basis of my Web.Config (stripped down without
comments):

<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
    <appSettings>
         <add key="ConnectionString" value="User ID=userid;Initial
Catalog=dbname;Data Source=servername.net;password=userpassword" />
    </appSettings>

    <location path="ForgotPswd.aspx"><system.web><authorization><allow
users="*" /></authorization></system.web></location>

    <system.web>
            <sessionState mode="InProc"
                          timeout="30" />
            <compilation debug="true"/>
            <customErrors mode="Off"/>

            <authentication mode="Forms">

                    <forms name=".ASPXAUTH"
                           loginUrl="login.aspx" />
            </authentication>

            <authorization>
               <deny users="?" />
            </authorization>
    </system.web>
</configuration>

Additionally, I have this in the Page_Load of the web page:
Response.AddHeader("Pragma", "no-cache")
Response.Expires = -1
Response.Expiresabsolute = Now().Subtract(New TimeSpan(1, 0, 0, 0))
Response.CacheControl = "no-cache"

Do you see any reason why it would expire unless they truly had 30 minutes
of no activity submitted to the server? Is there anything wrong here?
Thanks.
