} XHR_PROPERTY;

Constants

XHR_PROP_NO_CRED_PROMPT Value: 0 Sets a flag in the HTTP request that suppresses automatic prompts for credentials.
XHR_PROP_NO_AUTH Value: 0x1 Sets a flag in the HTTP request that configures the HTTP request that disables authentication for the request.
XHR_PROP_TIMEOUT Value: 0x2 Sets the connect, send, and receive timeouts for HTTP socket operations. Note  This value will not affect the timeout behavior of the entire request process.

XHR_PROP_NO_CACHE Value: 0x5 Suppresses cache reads and writes for the HTTP request.
XHR_PROP_EXTENDED_ERROR Value: 0x6 Causes the HTTP stack to provide HRESULTS with the underlying Win32 error code to the OnError callback method in case of failure.
XHR_PROP_QUERY_STRING_UTF8 Value: 0x7 Causes the query string to be encoded in UTF8 instead of ACP for HTTP request.
XHR_PROP_IGNORE_CERT_ERRORS Value: 0x8 Suppresses certain certificate errors.
XHR_PROP_ONDATA_THRESHOLD Value: 0x9
