Cannot get Session State to work

I've been on this for a while, and cannot figure it out. Can someone please
help with this message?

SessionState can only be used when EnableSessionState is set to true, either
in a configuration file or in the page directive. Please also make sure that
System.Web.SessionStateModule or a custom session state module is included in
the <configuration><system.web><httpModules> section in the application
configuration.

Here is my current web.config file

<?xml version="1.0"?>

re:
!> Not sure what you mean, but I do not have an InProc entry in my web.config file.

InProc is *also* the default.

If you want to disable SessionState *or* enable a different sessionState
management mode, other than InProc, you'll need to explicitly set those options.

Check to see if :

<section name="sessionState" type="System.Web.Configuration.SessionStateSection, System.Web,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" allowDefinition="MachineToApplication" />

....is in your machine.config file...it should be there.

I checked, and that entry is in my machine.config file. I still get the same
error about session state.
 
In my web.config, that was posted with my original quesiton, I have a
reference to Ajax, which I just added to my site. If I remove that and add
the below statement, my Session State works. How can I work this into my
web.config file? I've tried many combinations, but none worked. Or am I
looking in the wrong direction on how to fix this?

<pages enableSessionState="true" enableViewState="true"
enableViewStateMac="true" validateRequest="false" />
 
Try this :

<sessionState mode="InProc" cookieless="false" regenerateExpiredSessionId="false" timeout="20" />

If you don't mind Session ID's being reused, you can do with :

<sessionState mode="InProc" cookieless="false" timeout="20" />

That did not work. The only thing that works is the original line that I had
before I added Ajax entries. See below...

Original (Session state works, but I get a sys not defined on my Ajax pages):
<pages enableSessionState="true" enableViewState="true"
enableViewStateMac="true" validateRequest="false" />

Ajax Version (Ajax works, but now my Session State does not work):
<pages>
<controls>
<add tagPrefix="ajaxToolkit" namespace="System.Web.UI"
assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>
<add namespace="AjaxControlToolkit" assembly="AjaxControlToolkit"
tagPrefix="ajaxToolkit"/>
</controls>
</pages>

How can I incorporate the original session entry with the Ajax entries, and
have both things working at the same time?

Thanks a lot for your help.

Click to expand...


Just a guess, but maybe just add the attributes from your original "pages"
element to the working AJAX config like this:

<pages enableSessionState="true" enableViewState="true"
enableViewStateMac="true" validateRequest="false">
<controls>
<add tagPrefix="ajaxToolkit" namespace="System.Web.UI"
assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>
<add namespace="AjaxControlToolkit" assembly="AjaxControlToolkit"
tagPrefix="ajaxToolkit"/>
</controls>
</pages>
 
That's actually pretty easy Wannabe...

Try this:

<pages enableSessionState="true" enableViewState="true"
enableViewStateMac="true" validateRequest="false">
<controls>
<add tagPrefix="ajaxToolkit" namespace="System.Web.UI"
assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>
<add namespace="AjaxControlToolkit" assembly="AjaxControlToolkit"
tagPrefix="ajaxToolkit"/>
</controls>
</pages>
 
Thanks a lot...I am working on this all day, then all the sudden get two good
answers Thanks again Mike and Scott.
