Editing OpenSimulator Internals/Connector Architecture/Inventory Connector (section)

=== Transport ===

Unlike other connectors, XInventoryServicesConnector does not use SynchronousRestFormsRequester. It has its own MakePostDicRequest() method using HttpClient directly.

MakePostDicRequest() features:
* Uses WebUtil.GetNewGlobalHttpClient() with configured timeout
* Sends Keep-Alive headers (timeout=30, max=10)
* Sends Content-Type: application/x-www-form-urlencoded
* Uses HttpCompletionOption.ResponseHeadersRead -- reads headers first, then streams body
* Body receive has its own CancellationTokenSource timeout via WebUtil.EstimatedReceiveTimeout()
* Logs requests taking longer than WebUtil.LongCallTime
* Logs body timeouts separately from other errors
* Always disposes request, response, and client in finally block
* Returns empty Dictionary on null response (never returns null)

All requests are POST to m_InventoryURL. The METHOD and parameters are encoded as URL query string in the POST body.

MakeRequest() increments RequestsMade counter on every call.
