    <p>I currently have an IIS hosted application that I would like to switch over to use the self-hosted method.</p> <p>But I'm having difficulty accessing the session so I can retrieve the current users username.</p> <p>This is the code I used when hosting under IIS which worked perfectly:</p> <pre><code>/// &lt;summary&gt; /// A basic wrapper for the service stack session, to allow access to it lower down in the DAL layer without tying us to servicestack. /// &lt;/summary&gt; public class ServiceStackAuthTokenService : IAuthTokenService { /// &lt;summary&gt; /// GetCurrentAuthToken. /// &lt;/summary&gt; /// &lt;returns&gt;A string representing the users auth name.&lt;/returns&gt; public string GetCurrentAuthToken() { // Grab the current request. var req = HttpContext.Current.Request.ToRequest(); var res = HttpContext.Current.Response.ToResponse(); // Fetch the authentication service. var authService = EndpointHost.AppHost.TryResolve&lt;AuthService&gt;(); authService.RequestContext = new HttpRequestContext(req, res, null); // Grab the session. var session = authService.GetSession(false); // Return the username. return session.UserName; } public string UserPropertyName { get { return "UserName"; } } } </code></pre> <p>This is added to the app host with the following code::</p> <pre><code>container.RegisterAutoWiredAs&lt;ServiceStackAuthTokenService, IAuthTokenService&gt;() </code></pre> <p>When running self-hosted the HttpContext.Current is null, how do I access the request under a self-hosted application?</p> <p>Thanks!</p> <p><strong>Update</strong> Additional things I have tried:</p> <p>as per an post here: <a href="https://groups.google.com/forum/#!msg/servicestack/jnX8UwRWN8A/_XWzTGbnuHgJ">https://groups.google.com/forum/#!msg/servicestack/jnX8UwRWN8A/_XWzTGbnuHgJ</a></p> <p>It was suggested to use: </p> <p>container.Register>(c => AuthService.CurrentSessionFactory);</p> <p>This just returns a newed IAuthSession.</p> <p>What the user in that post is doing is exactly what I'm trying to achieve. </p> <p>In the last post Mythz says: </p> <p>Just to be clear, in order to form the Session Key that references the Users session you need either the ss-id or ss-pid cookies (as determined by ss-opts). You can get cookies off the IHttpRequest object or otherwise in ASP.NET the HttpContext.Current.Request singleton, so whatever IAuthUserSession factory you inject needs to take something that can give it the cookies, i.e. either an IRequestContext, IHttpRequest, IService, etc.</p> <p>But I still cant see a way to access the IHttpRequest.</p>

    1. COWhen/Where does GetCurrentAuthToken() get called in your application? If it's in a Service you could pass IHttpRequest and IHttpResponse into the method like GetCurrentAuthToken(base.Request, base.Response).

    2. COHi Paaschpa, It occurs in the DAL layer which has no direct relationship back to the service layer. I could pass the context into the DALs but that would violate the design and keep each layer separate.

    3. COHaving look into this further, I can see the IHttpRequest and the IHttpResponse is being injected into service via the IRequiresRequestContext interface that is in the service base class. I basically want to be able to access the same thing so I can get access to the cache where the client session is stored.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
