## Appendix: Develop locally with IE
If you develop angular locally with `ng serve`, a `websocket` connection is set up automatically between browser and local dev server, so when your code changes, the browser can automatically refresh.
If you develop Angular locally with `ng serve`, a `websocket` connection is set up automatically between browser and local dev server, so when your code changes, the browser can automatically refresh.
In Windows, by default, one application can only have 6 websocket connections, <a href="https://msdn.microsoft.com/library/ee330736%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396#websocket_maxconn" title="MSDN WebSocket settings">MSDN WebSocket Settings</a>.
So when IE is refreshed (manually or automatically by `ng serve`), sometimes the websocket does not close properly. When websocket connections exceed the limitations, a `SecurityError` will be thrown. This error will not affect the angular application, you can just restart IE to clear this error, or modify the windows registry to update the limitations.
