Send a Staged REST Request from a StringBuilder

See more REST Examples

Demonstrates Rest.SendReqSb, which sends a request whose text body is read from a StringBuilder, then reads the response in separate steps.

integer li_rc
integer li_Success
oleobject loo_Rest
integer li_BTls
integer li_BAutoReconnect
oleobject loo_SbBody
integer li_StatusCode

//  After sending, read the response status line and header fields.  The return value is the HTTP
