postParams property
The parameters from a 'application/x-www-form-urlencoded' request: typically from a POST request from a HTML form.
This is not null if the context is a request with a MIME type of 'application/x-www-form-urlencoded'.
Typically, this is associated with a POST request. For example, from a HTML form submitted with "method=POST". But there can be other HTTP methods that use that format; and there can be POST requests that do not use that format (e.g. POST requests with JSON in the body). Therefore, the name "postParams" is sometimes incorrect, but it is a nicer name than "xWwwFormUrlencodedParams".
Implementation
