You can edit this file to modify or add new commands. // // The original version of this file is named SampleRules.js and it is in the // \Program Files\Fiddler\ folder. When Fiddler first starts, it creates a copy named // CustomRules.js inside your \Documents\Fiddler2\Scripts folder. If you make a // mistake in editing this file, simply delete the CustomRules.js file and restart // Fiddler. A fresh copy of the default rules will be created from the original // sample rules file. // GLOBALIZATION NOTE: // Be sure to save this file with UTF-8 Encoding if using any non-ASCII characters // in strings, etc. // JScript.NET Reference // http://fiddler2.com/r/?msdnjsnet // // FiddlerScript Reference // http://fiddler2.com/r/?fiddlerscriptcookbook // // FiddlerScript Editor: // http://fiddler2.com/fiddlerscript-editor class Handlers { // The following snippet demonstrates a custom-bound column for the Web Sessions list. // See http://fiddler2.com/r/?fiddlercolumns for more info /* public static BindUIColumn("Method", 60) function FillMethodColumn(oS: Session): String { return oS.RequestMethod; } */ // The following snippet demonstrates how to create a custom tab that shows simple text /* public BindUITab("Flags") static function FlagsReport(arrSess: Session[]):String { var oSB: System.Text.StringBuilder = new System.Text.StringBuilder(); for (var i:int = 0; i-1)) { // Case sensitive oSession.url = oSession.url.Replace(gs_ReplaceToken, gs_ReplaceTokenWith); } if ((null != gs_OverridenHost) && (oSession.host.toLowerCase() == gs_OverridenHost)) { oSession["x-overridehost"] = gs_OverrideHostWith; } if ((null!=bpRequestURI) && oSession.uriContains(bpRequestURI)) { oSession["x-breakrequest"]="uri"; } if ((null!=bpMethod) && (oSession.HTTPMethodIs(bpMethod))) { oSession["x-breakrequest"]="method"; } if ((null!=uiBoldURI) && oSession.uriContains(uiBoldURI)) { oSession["ui-bold"]="QuickExec"; } if (m_SimulateModem) { // Delay sends by 300ms per KB uploaded. oSession["request-trickle-delay"] = "300"; // Delay receives by 150ms per KB downloaded. oSession["response-trickle-delay"] = "150"; } if (m_DisableCaching) { oSession.oRequest.headers.Remove("If-None-Match"); oSession.oRequest.headers.Remove("If-Modified-Since"); oSession.oRequest["Pragma"] = "no-cache"; } // User-Agent Overrides if (null != sUA) { oSession.oRequest["User-Agent"] = sUA; } if (m_Japanese) { oSession.oRequest["Accept-Language"] = "ja"; } if (m_AutoAuth) { // Automatically respond to any authentication challenges using the // current Fiddler user's credentials.
