First AJAX PageMethod blocks second page method from executing

[=?Utf-8?B?Um9nZXIgTWFydGlu?=]

In an earlier thread (http://tinyurl.com/33horg) I learned that when session
is enabled on a web page, a second page method is blocked until the first one
is complete.

Is there any way around this limitation, besides disabling session at the
page level?

Defining a method like the following doesn't solve the problem because
session is already disabled by default for a page method:

[System.Web.Serv ices.WebMethod( EnableSession=f alse)]
public static void WebMethod2()
{
System.Threadin g.Thread.Sleep( 5000);
}

you could write your own session state provider that allowed concurrent
session access, but you'd need to change your pages to use locking
when accessing a session variable.

Hi Roger,

If the page only needs read-only access to the session state, you can use
EnableSessionSt ate="ReadOnly" to enable concurrent access to the session
state; otherwise, you will have to implement your own session state
provider as Bruce suggested.

You can find more information here:

Thanks. I ended up modifying the page to not use session state.
