I have just installed FIDDLER v4.6 (under C:\Program Files (x86)\Fiddler2.) When starting up it gives below message. Rather than add relevant permissions to that network path, I'd rather re-config so the path is on local drive. However, I can't find a relevant config under Preferences tab; is it configured within REGEDIT, i.e. to define startup and/or script paths ?? Thanks in anticipation.

Hello,

When I open a URL in the browser (Internet Explorer), using FiddlerCore I can get all the raw HTTP requests/responses. However I would like to identify the time when a Web Page is completely loaded in the browser. Is it possible to do this? Is there any event which I can attach to?

Thanks

Shashank

So I'm on a server with no internet access (trying to debug an intranet application).

In Fiddler Options, OI have "Check for updates on startup" cleared, and "Offer upgrade to beta versions" cleared as well. Seconds after starting it, I get an exception:

Shouldn't it, y'know, not be checking for updates when I explicitly told it not to? Application dies, game over...

I've noticed within the last couple of updates, my filter *accounts.google.com:443 (set to "Hide the following hosts") is still showing in Fiddler.  Thoughts?

Using Fiddler Core with C# Application, I want to achieve the following ::


If a request URL matches the word "upgrade1.zip" , then i want to AutoRespond it with another zip file (say upgrade2.zip) which is in local path of my computer.



For Example : 


If request matches "upgrade1.zip" as in ::


http://somedomain.com/path/upgrade1.zip


then i want to auto respond with "upgrade2.zip" which is in the path ::


C:\Users\Desktop\upgrade2.zip


Please help with the steps!!


Attached a screenshot of the Autorespond condition i want to achieve

After I remapped the host, the Fiddler give me a HTTP 504, who can tell me how to solve it,please

 

 

 

Hi, I am running fiddler4.2.6 on windows server 2008. When I open a website with IE, it cannot open any images of the website. But IE works well when fiddler closed. I don't know why?

Ello, I'm a newbie at Fiddler and have been using it for sometime and loving it!

I've been trying to figure out a way to sort captured sessions that
I find in the "find sessions" window by it's color as it's a chore scrolling
through a lot of sessions that range in the hundreds and all.

I tried creating a custom column using the "custom column creator" but
don't know of a way to make it work with ui-backcolors or whatnot.

Then I tried using customRules to create a custom column in
with the FiddlerScript but...I'm really new to .NET and even after
some research, still haven't figured out a way to do it.

Here's my code that I modify from the sample codes used for
making custom columns.

public static BindUIColumn("BackColor")
           function CalcMethodCol(oS: Session) {
                  if (null != oS["ui-backcolor"]) return oS["ui-backcolor"]; else return String.Empty; 
        }

 

For other functions when it comes to sorting, I can likely find a way to do it (sorting urls and all) but for background colors...
This is something I have no idea what to do.

Can anyone kindly help?
This can be very useful when it comes to sorting any found sessions
without the need of scrolling any list big or small. That and other stuff!
