[Mono-devel-list] HttpWorkerRequest

[Joe Audette]

Gonzalo,
 
That may be true when you inherit from HttpWorkerRequest but when you call it directly on windows GetPreloadedEntityBody returns a byte array not null. I step through the code to verify this and the code never raises an error on windows because it never returns null.
 
This is the code that gets a reference to HttpWorkerRequest before it is passed into the RequestStream class:
 

HttpWorkerRequest GetWorkerRequest(HttpContext context)

{



IServiceProvider provider = (IServiceProvider)HttpContext.Current;

return (HttpWorkerRequest)provider.GetService(typeof(HttpWorkerRequest));

}

So in my observation mono does not produce the same behavior as windows .net, therefore this code works on windows but not mono. On Windows if you call directly HttpWorkerRequest.GetPreLoadedEntityBody it does not return null.

I urge you to download the code and its sample project and see how it works under windows but not on mono.

I think you're misundertanding. That method is already implemented in
HttpWorkerRequest.cs. It just returns null. That's the implementation.
You can easilly test that is the behavior that MS NET has in that method
of HttpWorkerRequest class. How? Derive your own class from
HttpWorkerRequest and call GetPreloadedEntityBody(). You'll always get
null.

Moreover, you have HasEntityBody() and IsEntireEntityBodyIsPreloaded()
to know in advance if GetPreloadedEntityBody() can be null.
