Hi,
Hi I am using Progress Telerik Fiddler Web Debugger version v5.0.20182.28034 for .NET 4.5 and I am unable to capture Https service wherein I can easily capture the HTTP traffic. The application for which I am capturing traffic is an ASP Dot net Core web application having version ASP.NET and Web Tools 2017 version 15.9.1 Microsoft Visual studio Enterprise 2017. I am facing issues in capturing Https traffic in spite of installing the root certificate and changing the system proxy for each protocol (HTTP, HTTPS, FTP) settings to 127.0.0.1:8888. Kindly help me with this.

I'm using Fiddler v4.6.20173.38786 (Built: Friday, September 15, 2017). When I click on the Customize Rules menu entry there is a message box that says "Unable to load Fiddler for code-completion support". After I click OK to that the Fiddler script editor will open normally.

Please package Fiddler with Homebrew Cask (https://github.com/Homebrew/homebrew-cask) , or at lease permit them to distribute the binary. Currently they are concerned about distributing Fiddler (https://github.com/Homebrew/homebrew-cask/pull/41374) .

Fiddler swaps out the real proxy settings for localhost when in use. When you disconnect or close it, it restores the proxy settings. However, if the system crashes or power fails while Fiddler is in use, upon rebooting the real proxy settings are of course missing, they're still set to localhost. I would expect that if were to then run Fiddler, it would find those proxy settings again so that if I run Fiddler and close it again, my original proxy settings would be restored. Sadly this doesn't happen so in this scenario I have to manually set up my proxy settings again. Can this be implemented?

I want to set the maximum session count to keep. Add some option in the configuration like "Max sessions to keep" so I can choose it from the menu "Keep sessions". Right now maximum session count I can choose is 10000 but it's too small value for me.

Office365 capturing stops when access token expires, blocking office refresh token?

After 1 hour the access token expires and from that point on Outlook (office365) just starts getting 401 unauthorised responses and outlook stops working (don't get this when fiddler is not running). Other people on forum also saying they have seen the same issue.

I unchecked the "check for updates" box for a reason. It's just too much overhead and interrupts my productivity to have to stop and deal with an update before going and debugging the thing I'm working on. Even if the version is old, I'd rather just keep working than be interrupted.

HTTP/2 has been a standard since mid-2015.   All major browsers support it,  but adoption is slow because there no good debugging tools.    I want to take advantage of pipelining, server push, etc that comes with HTTP/2 which makes it easier to adopt packages like gRPC.    Having a good debugging story (both capture as well as insertion / modification) would make this more possible

Today, CONFIG.sDefaultBrowserExe and sDefaultBrowserParams are internal, default to Internet Explorer and they don't seem to be controlled by preferences.

There should be a preference like fiddler.ui.toolbar.BrowserList.Default and fiddler.ui.toolbar.BrowserListDefaultParams that allows override.

Not much more to say. Fiddler on Windows is absolutely awesome, but nothing comes close on Max OS X.

Please, please, please offer a native Mac OS X version. I'd hiply pay 4100 or more for it. I'd even pay that for an annual subscription.

In order to debug a website served on localhost by IIS Express you need to use localhost.fiddler to get traffic to show up in Fiddler, but if you use HTTPS you'll first get a warning that the certificate name does not match and you have to manually confirm this connection.

This is generally a good idea, but in the case of localhost and localhost.fiddler I think this warning should not be shown, as having to use localhost.fiddler is simply a technical restriction that Fiddler should know about...

I accept your update and get to the install part and Windows 10 tells me that the update has an invalid certificate (or something).

Please remove popups that open when opening fiddler, for example the update prompt, and the survey prompt that showed up today.

Please honor the option to disable capture. I use fiddler to test API development and I never want it to capture any other traffic.  The configuration option to disable this doesn't work, please fix.

Repro:

1. Save a JPEG on your desktop as foo.Jpg

2. Drag drop file to Fiddler

Observe:

- File does not have correct Content-Type response header.

File extensions should be treated as case-insensitive when mapping to MIME types (Utilities::ContentTypeForFileExtension).

3. Rename a text file to foo.map

4. Drag drop file to Fiddler

Observe:

- File does not have correct Content-Type response header from the registry.

It looks like the registry may not be getting consulted properly; perhaps this was done with the introduction of CustomMimeMappings.xml which was presumably added to better support running on Mono/Linux, but Fiddler should still fall back to the Windows registry on Windows.

Today, you have to write annoying code like:

if (((oSession.responseCode == 301) ||
   (oSession.responseCode == 302) ||
   (oSession.responseCode == 303) ||
   (oSession.responseCode == 307) ||
   (oSession.responseCode == 308))  { ... do redirect stuff }

It would be better if there were a way to test a bunch of codes at once in an Enumerable (e.g. oSession.ResponseCodeIn([301,302,303,307,308])

It would also be nice if you could do:

if (oSession.oResponse.IsStatusRedirect() || oSessionl.oResponse.IsStatusClientError() || oSession.oResponse.IsStatusServerError() || oSession.oResponse.IsStatusSuccess())

...where each method returns true for 3xx, 4xx, 5xx, and 2xx.
