Explain what limitations are there for posting

[Valve]

The source code comment says:

If you wish to send a request body (e.g. POST requests), I'm sorry to have to tell you that there is
not good support for this yet. However, it can be done; here is an example:

Please update the readme and/or documentation with a description of these limitations.
The comments say that there are, but it's unclear what they are.

I think "not good support" in this case is short for "a lack of a convenient and typesafe request.set_body(...) kind of method or similar solution". The example shows that it's possible, but not as nice as it could be. Am I right, @chris-morgan?

That is correct. That’s what is meant there.
