CONFIG

Version information for the Fiddler/FiddlerCore assembly

Declaration

public static Version FiddlerVersionInfo

Field Value

Controls whether a Session may be resent on a different connection because reading of the response did not succeed. Default is to always retry.

Declaration

public static RetryMode RetryOnReceiveFailure

Field Value

Controls whether Fiddler will attempt to log on to the upstream proxy server to download the proxy configuration script

Declaration

Field Value

Controls whether Certificate-Generation output will be spewed to the Fiddler Log

Declaration

public static bool bDebugCertificateGeneration

Field Value

Set to true to force Fiddler Core to emit extra debugging information while capturing sessions

Declaration

public static bool bDebugSpew

Field Value

Boolean controls whether Fiddler should map inbound connections to their original process using IPHLPAPI

Declaration

public static bool bMapSocketToProcess

Field Value

Use 128bit AES Encryption when password-protecting .SAZ files. Note that, while this encryption is much stronger than the default encryption algorithm, it is significantly slower to save and load these files, and the Windows Explorer ZIP utility cannot open them.

Declaration

public static bool bUseAESForSAZ

Field Value

Controls whether Fiddler will try to write exceptions to the System Event log. Note: Usually fails due to ACLs on the Event Log.

Declaration

public static bool bUseEventLogForExceptions

Field Value

Boolean controls whether Fiddler will attempt to use the Server Name Indicator TLS extension to generate the SubjectCN for certificates

Declaration

public static bool bUseSNIForCN

Field Value

SSL/TLS Protocols we allow the client to choose from (when we call AuthenticateAsServer) We allow all TLS protocols by default (Tls1, Tls1.1, Tls1.2, Tls1.3). We 'Bitwise OR' in the constants for TLS1.1, TLS1.2 and TLS1.3 because we still build for .NET4.0.

Declaration

public static SslProtocols oAcceptedClientHTTPSProtocols

Field Value

SSL/TLS Protocols we request the server use (when we call AuthenticateAsClient). By default, TLS1, TLS1.1, TLS1.2 and TLS1.3 are accepted.

Declaration

public static SslProtocols oAcceptedServerHTTPSProtocols

Field Value

The encoding with which HTTP Body should be parsed. Defaults to UTF8

Declaration

public static Encoding oBodyEncoding

Field Value

The encoding with which HTTP Headers should be parsed. Defaults to UTF8, but may be overridden by specifying a REG_SZ containing the encoding name in the registry key \Fiddler2\HeaderEncoding

Declaration

public static Encoding oHeaderEncoding

Field Value

Alternative hostname which Fiddler should recognize as an alias for the local machine. The default value of ? will never be usable, as it's the QueryString delimiter

Declaration

public static string sAlternateHostname

Field Value

The password to send to the upstream gateway if the Version Checking webservice request requires authentication

Declaration

public static string sGatewayPassword

Field Value

The username to send to the upstream gateway if the Version Checking webservice request requires authentication

Declaration

public static string sGatewayUsername

Field Value

Controls whether Fiddler should register as the FTP proxy

Declaration

public static bool CaptureFTP { get; set; }

Property Value

Declaration

public static bool EnableHTTP2 { get; set; }

Property Value

Controls whether Fiddler will attempt to connect to IPv6 addresses

Declaration

public static bool EnableIPv6 { get; set; }

Property Value

Property Value

Controls whether server certificate errors are ignored when decrypting HTTPS traffic.

Declaration

public static bool IgnoreServerCertErrors { get; set; }

Property Value

Returns the path and filename of the editor used to edit the Rules script file.

The port upon which Fiddler is configured to listen.

Declaration

public static int ListenPort { get; }

Property Value

Controls whether Fiddler will reuse client connections for multiple sessions

Declaration

public static bool ReuseClientSockets { get; set; }

Property Value

Controls whether Fiddler will reuse server connections for multiple sessions

Declaration

public static bool ReuseServerSockets { get; set; }

Property Value

Should Audio/Video types automatically stream by default?

Declaration

public static bool StreamAudioVideo { get; set; }

Property Value

Gets a value indicating what mechanism, if any, will be used to find the upstream proxy/gateway.

Declaration

[Obsolete("Use Telerik.NetworkConnections.NetworkConnectionsManager.GetCurrentProxySettingsForConnection(*) to get information for the current proxy settings.")]
public static GatewayType UpstreamGateway { get; }
