Major Description
I found this when using the python "requests" library to generate HTTP requests to test the ATS. The request method of this library generates incorrect message body (i.e., does not follow the standard format) if both Content-Length and chunked encoding are specified. ATS can handle requests with these two fields being specified. It is the wrong format of the chunk that makes the ATS crash. The test program to reproduce the issue is attached. If the Content-Length is removed from the header, then the library generates the correct format and ATS responds correctly. Ideally, content-length and chunked encoding should not be specified together
