Property Value

Start a new proxy endpoint instance, listening on the specified port

Declaration

public static Proxy CreateProxyEndpoint(int iPort, bool bAllowRemote, X509Certificate2 certHTTPS)

Parameters

Returns

Start a new proxy endpoint instance, listening on the specified port

Declaration

public static Proxy CreateProxyEndpoint(int iPort, bool bAllowRemote, string sHTTPSHostname)

Parameters

Returns

Export Sessions in the specified format

Declaration

public static bool DoExport(string sExportFormat, Session[] oSessions, Dictionary<string, object> dictOptions, EventHandler<ProgressCallbackEventArgs> ehPCEA, bool logProgress = true)

Parameters

Returns

Calls a Fiddler Session Importer and returns the list of loaded Sessions.

Declaration

public static Session[] DoImport(string sImportFormat, bool bAddToSessionList, Dictionary<string, object> dictOptions, EventHandler<ProgressCallbackEventArgs> ehPCEA, GetPasswordDelegate passwordCallback = null, bool skipNewSessionEvent = false, bool logProgress = true)

Parameters

Returns

Gets Fiddler* version info

Declaration

public static string GetVersionString()

Returns

Allow working with the connectoids info. E.g. when you need info for the system proxies before starting the Fiddler one.

Declaration

public static void InitConnectoids()

Checks if FiddlerCore is running.

Declaration

public static bool IsStarted()

Returns

Checks if FiddlerCore is running and registered as the System Proxy.

Declaration

public static bool IsSystemProxy()

Returns

Record that a temporary file was created and handed to an external tool. We'll do our best to delete this file on exit.

Declaration

public static void LogLeakedFile(string sTempFile)

Parameters

Reset the SessionID counter to 0. This method can lead to confusing UI, so call sparingly.

Declaration

[CodeDescription("Reset the SessionID counter to 0. This method can lead to confusing UI, so call sparingly.")]
public static void ResetSessionCounter()

Set the DisplayName for the application

Declaration

public static void SetAppDisplayName(string sAppName)

Parameters

Shuts down the FiddlerCore proxy and disposes it. Note: If there's any traffic in progress while you're calling this method, your background threads are likely to blow up with ObjectDisposedExceptions or NullReferenceExceptions. In many cases, you're better off simply calling oProxy.Detach() and letting the garbage collector clean up when your program exits.
