C# Class Smrf.NodeXL.GraphDataProviders.HttpNetworkAnalyzerBase

Abstract base class for classes that analyze network information obtained via HTTP Web requests.

This base class implements properties related to HTTP Web requests, a BackgroundWorker instance, and properties, methods, and events related to the BackgroundWorker. The derived class must implement a method to start an analysis and implement the BackgroundWorker_DoWork method.
