WebPagePostFile Function

Action

Posts binary data to the Web server by means of the HTTP POST method. If the optional form for the query string includes a random variable, this function selects a new random value each time the form is posted. If the retrieved document is of content-type HTML, it is parsed and embedded documents are retrieved.

Instead of ASCII-encoded form content, binary data may be sent using this post function. The Content-Length header is automatically added to the request. The appropriate Content-Type has to be specified. In order to send binary data (octets) more safely over the Internet, use the WebBase64Encode function to convert the data to 6-bit ASCII characters.
