Status:Open Resolved:
Product:iOS SDK Product Version:7.0.x
Classification:Other Bug Reproducible:Always
 
Summary:
If a custom NSURLProtocol is provided to NSURLSession, even if the NSURLRequest has an HTTPBody non-nil when the request is passed to the NRURLProtocol (such as canInitWithRequest: or canonicalRequestForRequest:) has an empty body

Steps to Reproduce:
1. Create a subclass NSURLProtocol
2. Create an NSURLSessionConfiguration and set as protocolClasses an array containing the previously created NSURLProtocol
3. Create an NSURLRequest with HTTPMethod = @"POST" and with non-nil HTTPBody 
4. Create a NSURLSession and an NSURLSessionDataTask with the given NSURLRequest
5. resume the NSURLSessionDataTask

Expected Results:
When the method of the NSURLProtocol subclass are called the provided request should contains the previously set body

Actual Results:
The NSURLProtocol subclass method are called with a request with a nil body

Version:
iOS 7.0.x

Notes:
An example project is provided. The project demonstrate that with NSURLConnection the behavior is as expected, with NSURLSession the request has nil body

Worth nothing that Apple have demonstrated this field should be available in their example project:
