Return value
HTTP status of the request (
e.g. 200 for success, see HTTP standard specifications for a full list; value 999 indicates that an I/O error occurred during the operation) or the request number (≥1000) if asynchronous mode is active
Further information
1. The function returns after the request has been processed when synchronous mode is active (see
http_async). Otherwise, using asynchronous mode, the function returns immediately after having sent the request and the model is notified about the completion of the operation by an event of class
EVENT_HTTPEND. In this mode the result file
result must be a physical file (although drivers
"tmp:" and
"null:" can still be used).
2. The parameter
xhdr is typically used when the data type has to be specified. For instance, when the data sent is URL-encoded it may be necessary to use
"Content-Type: application/x-www-form-urlencoded" as the value for
xhdr in order to indicate to the server how to decode and process this data.
