On my Windows 8.1 Fiddler 4 (most recent version) only shows the splash screen and onle occasionally the warning dialog about Windows 8 when launching. After that it just crashes without any error message. I did not find any information about that in the event log.

How could I find out what the cause could be?

• I installed fiddler in windows 7.
  
  For example, I want to block videos that contain the word cats in the title. I also do not want the blocked videos appearing in:
  Recommended Channels tab
  Recommended/related videos
  Search results

• The tools that i used before moving to fiddler :https://chrome.google.com/webstore/detail/video-blocker/jknkjnpcbbgcbdbaampbjlhkcghmgfhk/details?utm_source=chrome-ntp-icon

 Thank you for your time

I cannot be the only one who is lost here ... but this is what I see when I try to get Fiddler.

"Fiddler4" is built for .NET 4, but installs as Fiddler2, and was just released "last month" (updated)
"Fiddler2" is build for .NET 2, and installs as Fiddler2, and was just released "last month" (updated)
"Fiddler2 Beta" is built for .NET 2, but says it is the upcoming version, but installs as just "Fiddler".

This is ... very confusing. Is there any chance we can get a clean, ironed out version in the future?

I have

set for all sessions in OnBeforeRequest(oSession: Session) and this works perfectly unless the session "was aborted by the client, Fiddler, or the Server". If the session is aborted, the request body is logged.

1. Should the body be dropped if it is an aborted session?
2. Is there a way of discarding the body even if the session was aborted?
3. Perhaps I should try dropping the body in OnPeekAtRequestHeaders(), OnReturningError() or even OnDone()?

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!
