Refactored NET request implementation.
- fixed potential issue with header conflict.
- simplified, and extract parts of the code into routine.
- Implemented read of chunked Transfer-Encoding
- Fixed potential issue with socket handling.
First steps to be able to exclude net or libcurl implementation when using http_client lib.
Removed from NET implementation the hack related to PUT and upload data (it was used to workaround an issue with libcurl).
before it was storing some header in the body.
now we added redirections: .. which is a list of redirection informations:
- status line
- header
- and eventual redirection body (but at least by default, libcurl does not cache body)
Enhanced the http_client library to be able to write directly the downloaded data into a file (or as convenient thanks to agent).
