# HTTP driver
This driver allows you to make http requests using the native HTTP client that is bundled with the
JVM. It supports free-form construction of requests.
This driver allows you to make http requests using the native HTTP client

You specify what a request looks like by providing a set of request parameters. They can be in
either literal (static) form with no dynamic data binding, or they can each be in a string template
form that draws from data bindings. Each cycle, a request is assembled from these parameters and
executed.

For those familiar with what an HTTP request looks like on the wire, the format below may be
familiar. This isn't actually the content that is submitted, but it is recognized as a valid way to
express the request parameters in a familiar and condensed form. A custom config parser makes this
form available fo rhose who want to emulate a well-known pattern:

Of course, in the above form, the response validators are still separate parameters.

## Bindings
All request fields can be made dynamic with binding functions. To make a request that has all
dynamic fields, you can do something like this:

The above example is in the inline request form. It is parsed and interpreted internally as if you

The above two examples are semantically identical, only the format is different. Notice that the
expansion of the URI is still captured in a field called uri, with all of the dynamic pieces
stitched together in the value. You can't use arbitrary request fields. Every request field must
from (method, uri, version, body, ok-status, ok-body) or otherwise be capitalized to signify an HTTP
header.

The HTTP RFCs do not require headers to be capitalized, but they are capitalized ubiquitously in
practice, so we follow that convention here for clarity. Headers are in-fact case-insensitive, so
any issues created by this indicate a non-conformant server/application implementation.
For URIs which are fully static (There are no dynamic fields, request generation will be much
faster, since the request is fully built and cached at startup.

- **method** - An optional request method. If not provided, "GET" is assumed. Any method name will
work here, even custom ones that are specific to a given target system. No validation is done for
standard method names, as there is no way to know what method names may be valid.

Java HttpClient is used. If it is provided, it must be one of 'HTTP/1.1' or 'HTTP/2.0'.
- **body** - The content of the request body, for methods which support it.
- **ok-status** - An optional set of rules to verify that a response is valid. This is a
simple comma or space separated list of integer status codes or a pattern which is used as a regex
against the string form of a status code. If any characters other than digits spaces and commas
are found in this value, then it is taken as a regex. If this is not provided, then any status

### Chunked encoding and web sockets
Presently, this driver only does basic request-response style requests. Thus, adding headers which
take TCP socket control away from the HttpClient will likely yield inconsistent (or undefined)
results. Support may be added for long-lived connections in a future release.
