Demonstrates how to upload files to an HTTP server using a multipart/form-data POST. AutoIt

Local $bSuccess = False

; This example requires the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.

$oHttp = ObjCreate("Chilkat.Http")

$oReq = ObjCreate("Chilkat.HttpRequest")
$oReq.HttpVerb = "POST"
$oReq.ContentType = "multipart/form-data"
$oReq.Path = "rcvFormDataUpload.aspx"

; Send an "Expect: 100-continue" header in the request.
; This causes the HTTP server to end a 100-continue response
; immediately after receiving the HTTP header.  The client
; (Chilkat) will receive this intermediate response, and if
; it's not an error response, it knows that the HTTP server will
; accept the data that is forthcoming.
; The alternative is to get an error response after trying to upload
; the entire contents of the files.
$oReq.AddHeader "Expect","100-continue"

; Call AddFileForUpload2 for each file to be uploaded in the HTTP multipart/form-data POST
; To allow Chilkat to determine the content-type automatically based on file-extension,
; call AddFileForUpload instead.

; The 1st arg is the filename passed in the HTTP request.
; The 2nd arg is the path in the local filesytem.
; The file is not loaded into memory.  It is streamed directly from the file
; when the HTTP POST is sent.
$bSuccess = $oReq.AddFileForUpload2("starfish.jpg","c:/qa_data/starfish.jpg","image/jpg")

; Its also possible to add a file from a string:
$bSuccess = $oReq.AddStringForUpload("test.xml","test.xml","<abc>This is the test.xml content</abc>","utf-8")
; We'll assume success since no files are involved..

; This sends the HTTP request (with 3 files being uploaded) to
; http://www.mywebserver123abc.com/rcvFormDataUpload.aspx
