Pause Web Sessions

Updated on Nov 6, 2025

To pause specific sessions, add rules using FiddlerScript to the OnBeforeRequest function (except where noted). For example:

Pause all HTTP POSTs to allow hand-editing (the POST verb is often used for submitting forms)

if (oSession.HTTPMethodIs("POST")){
	oSession["x-breakrequest"]="breaking for POST";
}

Pause all HTTP POSTs that contain 'thekeyword'

if (oSession.HTTPMethodIs("POST") && (oSession.utilFindInRequest("thekeyword", true) > -1)){
oSession["x-breakrequest"] = "keyword";
}

Pause a request for an XML file to allow hand-editing

if (oSession.url.toLowerCase().indexOf(".xml")>-1){
	oSession["x-breakrequest"]="reason_XML"; 
}

Pause a response containing JavaScript to allow hand-editing (in OnBeforeResponse)

if (oSession.oResponse.headers.ExistsAndContains("Content-Type", "javascript")){
	oSession["x-breakresponse"]="reason is JScript"; 
}
