* `OHHTTPStubs` **can't work on background sessions** (sessions created using `[NSURLSessionConfiguration backgroundSessionConfiguration]`) because background sessions don't allow the use of custom `NSURLProtocols` and are handled by the iOS Operating System itself.
* `OHHTTPStubs` don't simulate data upload. The `NSURLProtocolClient` `@protocol` does not provide a way to signal the delegate that data has been **sent** (only that some has been loaded), so any data in the `HTTPBody` or `HTTPBodyStream` of an `NSURLRequest`, or data provided to `-[NSURLSession uploadTaskWithRequest:fromData:];` will be ignored, and more importantly, the `-URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:` delegate method will never be called when you stub the request using `OHHTTPStubs`.
* `OHTTPStubs` **has a known issue with redirects** that we believe is an Apple bug. It has been discussed [here](https://github.com/AliSoftware/OHHTTPStubs/issues/230) and [here](https://github.com/AliSoftware/OHHTTPStubs/issues/280). The actual result of this bug is that redirects with a zero second delay may undeterministically end up with a null response.

_As far as I know, there's nothing we can do about those two limitations. Please let me know if you know a solution that would make that possible anyway._
