 It is possible to make HTTP (non-WebSocket) requests,

+In addition the [error codes](http://www.jsonrpc.org/specification#error_object)
 specified in the JSON-RPC spec, we use the following application specific error codes:
 
 code | message | meaning
 ---- | ------- | -------
 100 | Feature is disabled | The operation is unable to complete because a feature is disabled
 101 | VM must be paused | This operation is only valid when the VM is paused
 102 | Cannot add breakpoint | The VM is unable to add a breakpoint at the specified line or function
 103 | Stream already subscribed | The client is already subscribed to the specified _streamId_
 104 | Stream not subscribed | The client is not subscribed to the specified _streamId_
 105 | Isolate must be runnable | This operation cannot happen until the isolate is runnable

 ------- | --------
 1.0 | initial revision
 2.0 | Describe protocol version 2.0.
 3.0 | Describe protocol version 3.0.  Added UnresolvedSourceLocation.  Added Sentinel return to getIsolate.  Add AddedBreakpointWithScriptUri.  Removed Isolate.entry. The type of VM.pid was changed from string to int.  Added VMUpdate events.  Add offset and count parameters to getObject() and offset and count fields to Instance. Added ServiceExtensionAdded event.
 3.1 | Add the getSourceReport RPC.  The getObject RPC now accepts offset and count for string objects.  String objects now contain length, offset, and count properties.
 3.2 | Isolate objects now include the runnable bit and many debugger related RPCs will return an error if executed on an isolate before it is runnable.
 3.3 | Pause event now indicates if the isolate is paused at an await, yield, or yield* suspension point via the 'atAsyncSuspension' field. Resume command now supports the step parameter 'OverAsyncSuspension'. A Breakpoint added synthetically by an 'OverAsyncSuspension' resume command identifies itself as such via the 'isSyntheticAsyncContinuation' field.
 3.4 | Add the superType and mixin fields to Class. Added new pause event 'None'.
 3.5 | Add the error field to SourceReportRange.  Clarify definition of token position.
