Hi, all:

If URLMonInterop.SetProxyInProcess() set the proxy to a machine other than itself, will Fiddler capture the traffic?

What I need is after captureing the request, Fiddler throw it to a remote proxy server, and then waiting response. Is it possible? and how to fulfill?

I have an app that uses HTTPS and I can successfully use fiddler to view and modify the decrypted traffic. The app often does post requests of very large files (hundreds of MB or more) and fiddler seems to use loads of memory and become slow to respond when these large post requests are happening.

I'm hoping there is some way to not log the request/response body and just log the headers.

I have tried using stream mode which seems to make no difference; the body of the large request is still logged

I also added these two lines:
        oSession["log-drop-request-body"] = "yes";
        oSession["log-drop-response-body"] = "yes";
 to the OnBeforeRequest function. This results in the body not being logged after the request/response has completed, but while it is still going, the body is logged which is what causes the problem if the request is very large.

Is there anything else that I can try to make it behave better with these large posts?

Is there a way to filter the requests on the content of the request body for Post? 
I just want to autorespond to a certain body.

Hi there,

This is my first time using fiddler so apologies if I'm wrong anywhere...

I have to do 24 hour monitoring with Fiddler to capture an errant program which never seems to be working at any particular time.

Trouble is it does 5-7GB downloads in an hour and I need to locate it.

what is the capacity of Fiddler and how do I get it to right out on intervals?  Last nights 12 hour session seemed to loop and overwrite earlier entries

Many thanks in advance,

regards

Happy Friday!

I'm trying to use fiddler in the most automated way possible. I've set it up as a service, that works fine, I can see it running...etc. And I'm trying to get it to dump any data that it's collected to a _stored archive file. That also works. What ISNT working is one of two things, either the service has started (program running in the background) and it's not collecting against the user account i'm currently logged onto, or the program itself is not being shut down correctly to trigger the dump. at this moment, to stop the program I either need to kill the process in the task manager or stop the service.

Again, if I manually open fiddler and view the web, and close the program, it'll dump the info no problem. Does anyone have any ideas? this is to troubleshoot an issue some of my users are having that do not have the time to manually open fiddler when they start work, close it when the website crashes, and grab the dump for us to start sorting through.

any help is greatly appreciated!

Hi Everyone
I try fiddler with teleport pro 1.5.4 ,but fiddler can't capture the teleport traffic.Please tell me，What should I do？

Hi,
I'd like to save a complete raw response to a file with a little bit of extra debugging info added.
Looking at the demo app, its easy enough to get the FiddlerApplication_OnReadResponseBuffer and get the response data from that, but how can you correlate callback events to particular responses when a response is bigger than the 0x8000 buffer. In the past I have done this via netflows, but we don't seem to have access to server ip/port.

Any thoughts much appreciated.

Hello. There might be a potential problem with how Fiddler handles requests sent by CouchBaseClient constructor. Basically the observed behavior is that ctor hangs. See this SO discussion: http://stackoverflow.com/questions/21390152/couchbase-net-client-getting-stuck-in-the-constructor

Note: I have only ever used Fiddler on a desktop machine for debugging local HTTP / HTTPS calls.

One of my developers has been tasked with building a tunneling proxy / gateway to use on our guest network for the purposes of controlling outbound traffic (filtering on source / destination IP address, port number, etc.).  He insists that he is able to build on top of FiddlerCore and that FiddlerCore will handle all of the threading and events... basically acting as the engine of this proxy server.

Is this possible?  Can FiddlerCore be used in this way?  Do any sample projects exist to demonstrate this type of usage?

code working in fiddler,but not working in fiddlercore?


//init function
FiddlerApplication.BeforeResponse += onBeforeResponse;


//onBeforeResponse
private static void onBeforeResponse(Session oSession)
{
        if (oSession.url.IndexOf("/p_manager/")!=-1)
        {
                oSession.utilDecodeResponse();
                oSession.utilReplaceOnceInResponse("</body>", "<script>alert(1)</script></body>", false);
             //this code not working in fiddlercore,but this code in fiddler is working. i think maybe must append some code like
            //oSession["X-ResponseBody"] ,but i do not know how to do that.
            // i read fiddler's CustomRules.js but it not say how to do it.
           // i
           // recently ,in my hometown the google is no access. so i consult you again.
      
        }
