Session State and Webservices

[RicksAtWork]

In my global asax I have:

protected void Global_AcquireRequestState(Object sender, EventArgs e)
{

// set the security principal to our BusinessPrincipal
if(Session["CSLA-Principal"] != null)
{
Thread.CurrentPrincipal = (IPrincipal)Session["CSLA-Principal"];
HttpContext.Current.User = Thread.CurrentPrincipal;
}
}


If I navigate to a webservice, I get the error:

Session state is not available in this context.

I need the session code in my global.asax file for the rest of my site, but it seems to be causing issues with webservices

What am I doing wrong?

A web service is not the same as a web page, therefore does not have session state. You will need to pass any values you want to the webservice.

Okay, but since Global_AcquireRequestState will be called when I call the Web Service, this error will always occur.

Is there anyway of getting round this, other than moving the session related code out the method AcquireRequestState????

Ideally I would like to keep the code here since it is needed for page requests.

I don't know of any way. But then again, I have not used Web Services much. Maybe someone else can give you some tips on what you can do.

thats not entirely true: you can have user sessions, just add the enablesession attribute to the web method, like this:

[WebMethod(EnableSession=true)]
public string KillerMethod()
{...}

My error occurs before i specify a method - rather the problem occurs when i call the .asmx file without a reference to the method I want to execute.

Can you apply a similar tag to the whole webservice?
