* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loRest = CreateObject('Chilkat.Rest')

* Connect to the destination web server.
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("www.somewebserver.com",lnPort,lnBTls,lnBAutoReconnect)

* This example will send the following multipart/form-data request.
* The Content-Length is automatically computed and added by Chilkat.
* It will be different than what is shown here.
* The boundary string is also generated by Chilkat and will be different
* than shown below.
