HTTP POST Treatment of http:urlEncoded and http:urlReplacement

The HTTP Binding Component does not use the WSDL HTTP Binding consistently across GET and POST-style interactions, due to request structure differences between GET and POST requests.

The differences are:

• GET requests do not carry additional data aside from what is included in the URL (and in the HTTP headers).

• POST requests can send additional data in the request entity body. For example, when a web browser is used to submit a form (or upload a file through a form) by POST, the form data, or the contents of the file, is sent as the body of the request. The data is not made part of the request URL.

Because of these differences, the current HTTP Binding Component implementation considers http:urlEncoded and http:urlReplacement to be meaningful only when used in conjunction with HTTP GET, because these binding elements refer to URL encoding styles that apply only to GET requests.

For HTTP POST, the current implementation ignores both http:urlEncoded and http:urlReplacement binding elements.
