    Hello, I'm having an issue where Fiddler and FiddlerCore are missing specific HTTP traffic.

    I'm using both to determine where video players keep their video files by tracing the HTTP requests and issue takedowns on those locations. Problem is starting from at least last week, I am not seeing the requests/responses for these video files from a single website that I was once able to see in Fiddler or using FiddlerCore in my C# applications. I am seeing all other HTTP traffic, I have no filters on, and the missing requests are not HTTPS.

    An example URL is: http://megashare.im/watch-bhaag-milkha-bhaag-2013-online-free-megashare.html

    The video player on this page will make a HTTP request once clicked:

    GET /sec/QG3_yEC-vQTki3g6EJ14cw/1421136000/hls-vod-s3/flv/api/files/videos/2014/08/13/140787548142f4e.mp4.m3u8?socke.ts= HTTP/1.1\r\n

    Both Fiddler and FiddlerCore do not capture this request or its response. I was able to get the missing request by using WireShark:

    01.Hypertext Transfer Protocol
    02.    Expert Info (Chat/Sequence): GET /sec/QG3_yEC-vQTki3g6EJ14cw/1421136000/hls-vod-s3/flv/api/files/videos/2014/08/13/140787548142f4e.mp4.m3u8?socke.ts= HTTP/1.1\r\n
    03.      GET /sec/QG3_yEC-vQTki3g6EJ14cw/1421136000/hls-vod-s3/flv/api/files/videos/2014/08/13/140787548142f4e.mp4.m3u8?socke.ts= HTTP/1.1\r\n
    04.      Severity level: Chat
    05.      Group: Sequence
    06.    Request Method: GET
    07.    Request URI: /sec/QG3_yEC-vQTki3g6EJ14cw/1421136000/hls-vod-s3/flv/api/files/videos/2014/08/13/140787548142f4e.mp4.m3u8?socke.ts=
    08.    Request Version: HTTP/1.1
    09.  Host: c3.vkcache.com\r\n
    10.  Connection: close\r\n
    11.  
    13.  HTTP request 1/1

    I have noticed that when navigating to the example URL the Fiddler GUI logs many errors in this format:

    1.11:15:33:3909 [Fiddler] No HTTP request was received from (chrome:5372) new client socket, port 61461.
    2.11:15:33:3909 [Fiddler] No HTTP request was received from (chrome:5372) new client socket, port 61462.

    And FiddlerCore is also returning errors when I'm attempting to parse the Sessions when navigating to the example URL using Selenium in my C# application:

    1.The client failed to send a complete request before the timeout period elapsed.

    I'm not exactly sure why Fiddler isn't able to fully capture these video source URLs, but any help would be appreciated.

    Thanks,
    Anthony

    Unfortunately, our overzealous corporate firewall blocks access to the target site, so I can't see it from here. There are three possibilities:

    1> The target video is already in your cache, so it's not being downloaded again.
    2> The target video is playing back through some other application which doesn't (by default) respect the system's proxy settings and thus it must be manually configured to do so.
    3> The target video is actually downloading over some other protocol (Flash has a way to stream video directly on TCP/IP) and thus it doesn't run through a proxy.

    Based on the description alone, #1 or #2 seem most likely.

    Hello, Bahare--

    You really haven't given us anything to go on. Without more details, no one will be able to help you. What is the application? Where is the traffic sent? What does "I capture the attempt to run the app" mean? Are you able to successfully capture traffic from other applications? etc.

    I am facing the same issue. I am certain PUT requests we issue to upload items in Sharepoint do not show in Fiddler.

    Hi,

    Is the application you are using respecting the system proxy settings? If yes, do you have any filters set?

    Hi,

     

    I do not have filter and our application does honor IE settings.

    I am used to work with Fiddler for years, it recently stopped showing PUT request most of the time, it displays it something while nothing changed in terms of settings.

     

    Thanks,

    Hi,

    Do you any other requests (GET, POST) from your application? Does turning Help -> Troubleshoot on shows the missing PUT requests with striketrough font?

    Hi,

    I'm unable to reproduce the problem you have. Would it be possible that you create a sample app replicating this behavior?

    Hi Jean,

    Sorry for the late reply and thank you for providing us a with a way to reproduce the problem. I made a test with the latest version of Fiddler v5.0.20182.28034 and I was able to inspect the PUT requests which harmon.ie makes to upload files.

    Could you, please, try the latest version of Fiddler to confirm if the problem is fixed on your site, as well.

    Regards,
