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 with Global scope to create a new menu item as follows:

    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 in the OnBeforeResponse function as follows:

    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()); 
      } 
      } 
    }
