HTTPPostLoad(url,headers[],formFields[])

Although LoadFile allows you to load documents from web servers, you cannot specify the HTTP headers of your request.
HTTPLoad allows you to do so, by specifying a key based array of name/value pairs:

h["Accept"] = "*.*" $
h["Accept-Language"] = "en-us" $
h["User-Agent"] = "Aptilis/2.0" $
h["Host"] = _Host + ":80" $
h["Connection"] = "Close" $
h["Cache-Control"] = "no-cache" $

HTTPPostLoad will use the post method, and add the variables you specified to the request. To the web server, your request will look exactly as if it were coming from a web browser.

formfield["name"] = "teebo" $
formfield["creditCardNumber"] = "12345678910" $
page = httpPostLoad("http://www.someserver.com/cgi-bin/order.cgi", h[], formfield[]) $

Important note:
Even if you specify a content-length and a content-type in your request, they will be overwritten by Aptilis to reflect the appropriate content-type and length of your request as per the POST method.

Specifying a Url
Here is an http:// Url: "http://www.cnn.com/"

You can use IP numbers and port numbers as well to override the default ports for http:// (80), such as:
"http://www.xnn.org:8080/news/secret.html"

In the case of web pages, the document returned contains the page itself and its header. The end of the header is after the occurrence of the header delimiter: "\n\n", or possibly "\r\n\r\n". I usually remove the "\r" 's anyway:

file = replace(file$, "\r", "") $

Return Value:
The whole file if everything was OK.
An empty string in case of error and the _errno variable contains more details about the error.
