Hi. I am working with a web page that makes requests to an API and is returning a Json.

When I use the Fiddler it only shows me Tunnel to xxxxx: 443.

In the following elements, neither the request information nor the response with the Json appear. Is there any way to see it?

Hi,
I have been using fiddler from last 4 months and whenever I convert .saz file into .pcap it hides the Ethernet II information, as the picture is attached for the reference.

Hello. I need to know if you have how to migrate the settings of the fiddler in this case options such as the size of the window and the selected items such as removing encodings and etc. without the person having to redo these settings on her computer? Is there a registration key that makes this automatic? Thank you.

Hello Telerik,

 

I am using Fiddler tool for WebAPI testing. It is working fine but yesterday I faced one problem while sending long data in Request body. WebAPI allowing ArrayBytes data for images. Converted 22MB images into bytes and passing those bytes info as request. I observed that, unable to paste complete byte info into request body.

 

Is there any way to pass complete info using fiddler tool? Can you please help us.

Thanks in Advance.

I am developing a .Net application using FiddlerCore package. I setup a proxy where there are multiple clients(Internet Explorer) running to connect to a same server thru websocket.The proxy program is monitoring all those websocket messages, but is there any way to differetiate the websocket messages belong to which client process? Thank you.

Fiddler did not bring back my os settings when it crashed, moreover it did not restore them even after restarting the os. The problem is that fiddler itself also uses system proxy settings, so I can't run it to get my internet connection back.
How can I get my os settings back before using fiddler?
