Search Sequential Pages for Target String

To search for a target string on a series of successively named HTML pages (for example, to find the first page containing "TargetString" from 1.htm, 2.htm, 3.htm, 4.htm, etc.), add rules to Fiddler as follows:

1. Add a rule to Fiddler Classic with Global scope to create a new menu item as follows:

   C#

   public static ToolsAction("Find page containing search string") 
   function doGrab(){ 
   	var s = "GET /gallery/image1.htm HTTP/1.1\r\nHost: www.example.com\r\nX-My-Num: 1\r\n\r\n"; 
   	try{ 
   	FiddlerObject.utilIssueRequest(s); 
   	} 
   	catch(e){ 
   	MessageBox.Show("send failed" + e.ToString()); 
   	} 
   }

This will generate the first request. Note: Because the utilIssueRequest call is asynchronous, you don't get the response directly.

2. Add a rule to Fiddler Classic in the OnBeforeResponse function as follows:

   c#

   if (oSession.oRequest.headers.Exists("X-My-Num")){ 
   	// This is a response to my Grab code... 
   	if (oSession.utilFindInResponse("targetstring", false) > -1){ 
   	// If the index of the target string is >-1, we found the search string...  
   	MessageBox.Show("Found target string!");
   	} 
   	else 
   	{ 
   	//didn't find the target string.  increment the number. 
   	var n = int.parse(oSession.oRequest["X-My-Num"]); 
   	n++; 
   	var s = "GET /gallery/image" + n.ToString() + ".htm HTTP/1.1\r\nHost: http://www.example.com\r\nX-My-Num: "+ n.ToString() + "\r\n\r\n"; 
   	try{ 
   	// Make a recursive HTTP request for the next item.
   	FiddlerObject.utilIssueRequest(s); 
   	} 
   	catch(e){ 
   		MessageBox.Show("send failed" + e.ToString()); 
   	} 
   	} 
   }
