Session object is NULL in HTTPModule

[Guest]

ey,
I m trying to make a new httpmodule but the session object is null. I m
implementing IReadOnlySessionState but it keep on being null.

I m novice in this enviroment, does anybody know what's happening?

thanks

Miguel

It's likely a timing issue. Session isn't available until the
AcquireRequestState event.

Try hooking after this, such as the PreRequestHandlerExecute event

thank you karl,

buff, it doesn't work, I think I am doing what you have said but I dont get
the session: context.PreRequestHandlerExecute += (new EventHandler
this.Application_AuthenticateRequest));.

any ideas? I am a little bit lost :-(

thanks again

here is the source code:

public class SetIdentity : IHttpModule, IReadOnlySessionState
{
public void Init(HttpApplication context)
{
context.PreRequestHandlerExecute += (new EventHandler
this.Application_AuthenticateRequest));
}

private void Application_AuthenticateRequest(object source, EventArgs e)
{
HttpApplication application = (HttpApplication)source;

HttpContext context = application.Context;
HttpSessionState session = context.Session;

String cookieValue = "No session";
if (session != null) cookieValue = session.SessionID;
// Put it into a cookie
HttpCookie hc = new
HttpCookie("SessionSharePoint", cookieValue);
hc.Expires = DateTime.Now.AddMinutes(20);

// Add it to the cookies collection
context.Response.Cookies.Add(hc);


}
public void Dispose()
{
}


}

Your code works fine for me. session isn't null and cookie was being set...

I'm not the only one recommending my approach:

but, you don't seem to be the only one having problems:

Perhaps you can contact Alex and see if he ever solved his problem?

ey karl!

Know it is working. It was a problem with the web.config. There is a
parameter to false that must be true and a comment module in charge of the
sessionState.

Thank you

Web.config

Hi Miguel,
I know this post was from a while back, but I'm having the same exact issue. What were the lines in the web.config that you changed? Thanks for the clarification!

He means the cookieless attribute of the sessionstate element in your web.config.

this kind ofthing I think:

<httpModules>
<add name="DaoFactoryProvider" type="Capture.DaoProvider.DaoFactoryProvider"/>
</httpModules>
