> ATS-6.2.x crashes if the message-body of a chunk is not correctly formatted
> ---------------------------------------------------------------------------
>
> Key: TS-4819
> URL: https://issues.apache.org/jira/browse/TS-4819
> Project: Traffic Server
> Issue Type: Bug
> Components: Core
> Reporter: Syeda Persia Aziz
>
> 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. This problem can be reproduced using the python
> file 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
