RFC-7230 states that a Content-Length header is normally sent in
a POST request even when the value (length) is 0, indicating an
empty payload body. Rex HTTP client failed to follow this spec,
and caused some modules to fail (such as winrm_login).
Fix#6398
This patches changes two things:
1. If a module has a custom Content-Length, it will respect that
instead of forcing its own.
2. If a request does not have anything in the body, the
Content-Length header will not be set.
Fix#6609Fix#6587
not strictly required, these conversions keep us
up to date with latest rspec conventions and best practices
which will prevent use from having to convert them when they become
deprecated later
'hex-all' encoding was previously ignoring slashes.
This pull adds 'hex-noslashes' mode which carries forward the previous functionality, and replaces all existing references to 'hex-all' with 'hex-noslashes' It then adds a replacement 'hex-all' mode, which really encodes *ALL* characters.
They were identical except for a couple of extra bugs in set_cgi.
Also changes ```split("/")``` to ```split("/", -1)```, which behaves
correctly when the input has a seperator at the beginning or end.
