Question

I have written a simple REST API in WCF, and the authentication mechanism uses an API key. Once the client submits the API key in the request header, I check it on the server side (in the BaseService class overriding the ProcessRequest() method of RequestInterceptor class) as follows:

public partial class BaseService : RequestInterceptor
{
    public BaseService() : base(false) { }

    #region Process Request
    public override void ProcessRequest(ref RequestContext requestContext)
    {
        if (IsValidApiKey(requestContext))
           //put some values in HttpContext object.

     }

…

Now I have enabled aspnet compatibility in my REST services, but I still cannot access HttpContext object in the ProcessRequest override above.
Note that HttpContext is accessible from inside a service method, but not in the ProcessRequest method.

Any ideas why?

I have solved my problem by adding following code:

private HttpContext _httpContext;
public BaseService()
        : base(true)
    {
        _httpContext = HttpContext.Current;            

    }

After doing this I am able to access HttpContext object in the ProcessRequest method.
