Capture the Composed REST Request for Debugging

See more REST Examples

Demonstrates Rest.GetLastDebugRequest, which copies the fully composed HTTP request (request line, headers, and body) into a BinData. The example builds a two-part multipart request so the captured output shows the multipart boundaries, part headers, and part bodies. This works when the DebugMode property was enabled while the request was composed.

Dim success As Long
success = 0

Dim rest As New ChilkatRest

'  Copy the composed request (request line, headers, and multipart body that would be sent) into a
'  BinData, then view it as text.
