在ASHX处理程序上恢复会话值返回Null

Question

I have a .ASHX handler, that make some operations, and I need recover a specific information that are in the Session, so I do context.Session["key"] but always returns null the context.Session

I've try some configurations on Web.Config file like

<sessionState mode="InProc" customProvider="DefaultSessionProvider" cookieless="AutoDetect">

Or

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <remove name="Session" />
      <add name="Session" type="System.Web.SessionState.SessionStateModule"/>
    </modules>
  </system.webServer>

but without success, can anyone help me recover the Session value on .ASHX handler?

Answer 1

At your handler .ashx.cs code implement the interface IReadOnlySessionState

Example:

class Handler : IReadOnlySessionState { ...

That will not return null but the session
