WebPagePost 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.

Parameter	Description
sUrl	Absolute URL to the document on the server. All characters that are part of the query string are not URL-encoded.
sData	Data to post to the server. This may also be binary data. For posting all available binary data specify STRING_COMPLETE for nDataLength and use the bin() operator for sData (see example).
nDataLength	Amount of the data that is posted to the server (in bytes). Specify STRING_COMPLETE or omit this parameter to post all available data.
sContent	Content type string used in the request, for example, "image/gif".
sTimer	Name of the timer used for page measurements (optional). If this parameter is omitted, no measurements are performed.
formUrl	Form identifier used in the `dclform` section (optional). The expanded form is added to the URL after the "?".
