Please, help me. How to send request in code Fiddler JavaScript.net?

Good day! I got problems with installation fiddler certificate on my pc, if I export the certificate myself, it simply is not detected by the system and google chrome says that the certificate is not valid, when I try to click install automatically using the trust root certificate button, it gives an error, put a log in the files. Thanks in advance.

I faced the next issue: Fiddler doesn't decode Zstandard (ZSTD) encoded requests!
Help me, please, how to fix it?

Hey Fiddler community,

I made an extension to cache API responses right in fiddler to speed up your front-end (or backend :)) development. Me and my teammates have been using this for a couple of years and we found it very useful. Its very handy if you work with rate limited APIs or heavy/slow network calls.

I thought of sharing this with the community, and it might help you if you are looking for something like this. Its in early stages and still needs improvements, testing and feedback. I would love to hear from you if you decide to give it a whirl. Bug reports or pull requests are very welcome.

Its called NitroCacher and here's the link: https://github.com/sarathkcm/NitroCacher .

 

To the Telerik team: it would be cool to get it added to the add-ons page. Would it be possible for you to add it there? Taking cues from another thread, I'm adding the required information below:

Short Description: Fiddler add-on to cache API responses based on rules. Useful when working with rate limited APIs or heavy/slow API responses that take up a good amount of time during development.

Hi.

Is there an option to download standalone version of fiddler?

Hello,

I have a very strange problem that I have not managed to solve and am hoping someone can point me at the cause of our issue.  We have a Windows 8.1 UWP side-loaded application which connects to a central server over HTTP.  Let's call this Site A.  The UWP application in Site A connects to the central server succesfully. 

However, we have another location (called Site B) which runs the same UWP application but is unable to connect to the central server at Site A unless Fiddler is running.  Interestingly, Internet Explorer connects to the central server in Site A without fiddler running.

I understand Fiddler is a proxy and allows UWP application to be disabled from loopback check.

Please can someone help, what changes does Fiddler make to the Registry etc that would cause the UWP application in Site B to work?

Kind Regards,

 

Chris

Hi,

Im trying to decrypt SSL traffic and I keep getting an alternating SSL error.  It's either Subject Alternative Name missing or Common Name Invalid.

I've changed the engine to CertEnroll and cleared old certs, retsarted browser and Fid but no good.

The site I'm trying decrypt is part of an IIS WebFarm which uses Centralised Certificates so the SAN is needed to lookup the correct cert to perform the handshake so I think this is the issue.

Fiddler: 4.5.1.2

Chrome: 74.0.3729.131 32bit

 

Any ideas?

 

Many Thanks,

Brad

I have captured a few hundred requests that I would like to replay several hundred times (or just repeat ad infinitum).

My problem is that Fiddler always "captures" the new requests it makes so after a few minutes the list of requests is many tens of thousand long and Fiddler is using many GB of memory.In my case I am not that interested in inspecting the replayed request / response - I would like Fiddler to "fire and forget" them.

I have experimented with the "Keep: XXX Sessions" option as well as filtering to a random process option - but it seems that Fiddler always wants to record requests that it replays.

 

Is there a simple solution.

 

Thanks in advance 

 

Chris

 

 

I have read and tried every flavor I can find on how to make this work, but nothing does. I don't care about traffic leaving my server, on the requests coming into IIS for all sites listening on that server. AND all traffic inbound is SSL so its over port 443. We have nothing bound to port 80 at all. Every example I found only mentions port 80 and I suspect that is why its not working. What are the steps to get this to work on a Windows Datacenter Server 2016 server for request that come from external sources? 

The amount of times I am restarting fiddler and adding the same URLs or processes to filter out is getting a bit mundane. I have Outlook, Skype running which all clutter up the list.  Also IE is running.  I just want to focus on a single URL within a session.

Is there a filter list where I can save the filters to and easily switch on switch off this?
