Has anyone else had this problem?  I was using AutoResponder to test without having to reload on my test box every time I made a change - it was working.  I was redirecting from the web server on my VM to a share on my development machine (Y:\Dev\somescript.js).  Then, suddenly, with no changes to either machine other than the obvious code changes to somescript.js, I was getting 404 errors on the file.  If I change the redirect to a local drive (C:\Dev\somescript.js), the AutoResponder works fine - but this is really not an option for me, for several reasons.  I can open the file through the File Explorer on the VM, so the mapping is still there.

This happened to me before and after multiple hours of troubleshooting, I simply re-installed Fiddler and it started working again - for a while; now, re-installation doesn't even fix it. 

Obviously, I can work around it, by just re-deploying to my VM *every* time I make a change, but that adds a lot of steps and opportunity for error that I was able to work around when AutoResponder was working for me.

Further Info:  VM is Windows 2008 R2, Hardware Dev is Windows 7, running Internet Explorer 9, have even tried several of the spiffy tricks, like the localhost "dot trick", using ipv4.fiddler, etc (that I shouldn't need since I'm not on IE8, but desperate times and all that....)

Any help or suggestions would be greatly appreciated.

Hi Dears.

I'm used proxifer without any trouble , but after i install Fiddler it work only when fiddler is on otherwise it (proxifier) doesn't capture anything. How i can fix it ?

Thanks

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
• Visual sample : http://i.imgur.com/JBDOi3V.jpg
• 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
