You would have to use IAppHost.RawHttpHandlers
because that's the only custom handler in ServiceStack's Request Pipeline that gets executed before the built-in static file handling is accessed.
But you should still be able to access the Users Session with the available extension methods, e.g:
this.RawHttpHandlers.Add(httpReq =>
{
var isStaticFileRequest = httpReq.PathInfo.StartsWith("/static");
if (isStaticFileRequest)
{
var session = httpReq.GetSession();
if (!session.HasRole("TheRole"))
return new ForbiddenHttpHandler();
}
return null;
});
This handler simply checks if it's a request for a static file, in this case the path info starts with /static
, and if is checks the user session if they have the required role, if not it returns a Forbidden request, otherwise it returns null
to tell ServiceStack to continue executing the request.
Note: if it's needed you can access any registered dependency from outside of ServiceStack with HostContext.Resolve, e.g:
var authRepo = HostContext.Resolve<IAuthRepository>();
