# httpdel

Purpose
Perform an HTTP DELETE request.
Synopsis
`function httpdel(url:string|text, result:string):integer`
`function httpdel(url:string|text, result:string, xhdr:string|text):integer`
Arguments

url | URL to process
result | File to store the result of the request
xhdr | Additional headers to add to the request

Return value
HTTP status of the request ( e.g. 200 for success, see Section Constants for a list of predefined status code constants; value 999 indicates that an I/O error occurred during the operation) or the request number (≥1000) if the 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. When cookie management is enabled (see http_cookies) an additional header "Cookie:" is inserted into the request if the cookie store contains compatible cookies. This behaviour is disabled if this optional header is already specified via the parameter xhdr.
3. An IO error will be raised if the destination file cannot be accessed.
