Concatenation locations and parameters

Hello,
POST Tour returns a valid result with MSXML2.XMLHTTP60, how must i concatenate the global parameters like “speed” behind the locations?

locations=[{“address”:“The Hague, The Netherlands”,“lat”:“52.05429”,“lng”:“4.248618”},{“address”:“The Hague, The Netherlands”,“lat”:“52.076892”,“lng”:“4.26975”},{“address”:“Uden, The Netherlands”,“lat”:“51.669946”,“lng”:“5.61852”},{“address”:“Sint-Oedenrode, The Netherlands”,“lat”:“51.589548”,“lng”:“5.432482”}],[{“parameters[speed]”:80}]

The parameters should be posted as separate parameter. We’re no MSXML experts and we didn’t test, but we’d suggest to try something like:

locations=[{"address":"The Hague, The Netherlands","lat":"52.05429","lng":"4.248618"},{"address":"The Hague, The Netherlands","lat":"52.076892","lng":"4.26975"},{"address":"Uden, The Netherlands","lat":"51.669946","lng":"5.61852"},{"address":"Sint-Oedenrode, The Netherlands","lat":"51.589548","lng":"5.432482"}]&parameters[speed]=80
