I want to use PAC file. http://127.0.0.1:8888/proxy.pac, this way, if my proxy accidently quits without remove the proxy setting, the browser will be able to continue to work since it can't find the pac file, thus consider it "No proxy".

But When I set the flags, if I don't include: "RegisterAsSystemProxy", the PAC file will not registered.

If I DO include "RegisterAsSystemProxy", the PAC file is registered, but also the proxy servers, 127.0.0.1 8888 for http and https. What's the point to have both registered, and it negate my purpose.

Anyway to hook up PAC file only?

Also, how to  modify the PAC file content, for GOD's sake?

I read about fiddler everywhere and would really like to try it out.

The problem is that i work in a closed organization where we do not have internet access. In order to run the program there is a need to sign in which is not possible for me.

Is there any way around this?

I am sending a post request using angular to my api using chrome browser.but the request fails.when fiddler is running on my pc, post request is executed without any error.I enabled capture https request option.

I am not using any proxy. Anyone has an idea why this occurs?

I've added a session timer "Overall_Elapsed" column to my captured traffic.

Is there a way to filter requests by Overall_Elapsed time (or any of the session timers) that is greater than a specific value?

A difficult problem I am unable to overcome is separating traffic depending on which tab it's coming from. I am using Fiddler with Chrome, and this is what I'm trying to accomplish:

Lets say we have two tabs open, tab A, and tab B. I want method A to be run if there is HTTP/HTTPS traffic from tab A, and method B to run if there is HTTP/HTTPS traffic from tab B. Is there a way to distinguish between the traffic between tabs?

As a secondary question, is there a way to distinguish traffic between browsers as well? For example, separating Chrome traffic from Firefox traffic?

I have tried a lot of potential solutions. A few examples of what I've tried are: attempting to use filters, but this only blocks traffic from all other sources, except for a given table which is not the functionality that I need. I've also tried to figure out how to distinguish the two via FiddlerScript, but was unable to create anything useful. I have looked intoWebSocketMessage and Session data-structures, to no avail.

Is there a way to solve either of my two problems?

This issue was reported by someone using my app which user fiddler core but the issue also repro's on standalone fiddler.

Launch fiddler and go to a media server link like 

http://www.media-server.com/m/p/fbqsmu6b

The response returned is Fiddler] ReadResponse() failed: The server did not return a response for this request. Server returned 0 bytes.

I would like to know if there is a way to work around this issue using fiddler core.

Thanks,

Hello,

I have small problem, https decrypt works correctly for any website for example : google, facebook etc. but when I will try open https://api.revolut.com/ I got error : 

This site can’t be reached
The connection was reset.
Try:
Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics
ERR_CONNECTION_RESET

Do you have this same problem? Any Ideas?

After disable HTTPS Decrypt works correct. I have checked all protocols. 

Best Regards

I have a .net app (using framework 4.7.1) making a simple call to fetch images from various sites. One site for some reason will always timeout the request. But if I use Fiddler as a proxy, then it always works just fine. The image URL also works just fine in a browser. I'm aware of the various things to look for when Fiddler seems to 'fix' your app, but none of them seem to apply here. I have tried using different protocols in options ... https ... protocols to see if I could get Fiddler to also fail in the same way, but no luck, it always succeeds. Even if I uncheck 'capture https connects' it works. 

Any ideas what Fiddler could be doing to make it work so I can fix my app?

New to packet sniffing and network diagnostics ..... I have what I hope to be a simple request.

1.  I want to do some automation. However, I do not want to use cloud based only solutions.

2.  At the moment I have not particular tech in mind but it will be wifi ... as I do not have a smart home hub for zig-bee or z-wave or what have you.

3.  Thinking about starting here with this product: https://www.amazon.com/SmartDry-Wireless-Laundry-Clothes-Electric/dp/B07GQBW2KS/ref=pd_ybh_a_1?_encoding=UTF8&psc=1&refRID=1PES8E33EBRMBXN9BDVX

4.  Now it's wifi based and that means it has to go through my router to work.  Which means, I think, it should be simple url based traffic.  Can fiddler on my laptop be set up to intercept the traffic coming in to a smart phone and out of smartphone and in/out of my net work ( yes I'd have the phone set to use wifi data not phone data plan )


If there is a tutorial out there that more/less ( aka more ) discusses this I'd be grateful.  I'm struggling to get going with automation because it seems that every Tom, Dick, and Harry company just wants you to create an account so that they can pimp your data around.  I'd rather pay say $20 more for the tech rather than have to crack open my personal data.
