Capturing web traffic logs

If you've reached this page, chances are good that you were asked to capture a Web Traffic log. Usually, this action is performed to track down a bug in your web browser or a website.

You can use Progress® Telerik® FiddlerCap™ to capture your Web Traffic, and send that capture to a debugging buddy who can troubleshoot the bug.


Step-by-step guide


Download and install Telerik FiddlerCap.


FiddlerCap will start automatically when the installer completes.


(Optional) Inside FiddlerCap, click the Clear Cookies button and then the Clear Cache button.


(Optional) Inside FiddlerCap, check the Decrypt HTTPS Traffic box. Note that FiddlerCap uses the system proxy and installs & trusts the root certificate on an OS level. If you are using Firefox (or another browser that uses its own certificate store) then refer to the instructions here.


Inside FiddlerCap, click the  1. Start Capture  button.


Use the browser’s address bar to go to the site you need to reproduce the problem.


(Optional) Add a screenshot to your capture by clicking on the Screenshot button inside FiddlerCap. Add a comment by clicking on the Flag button.


Inside FiddlerCap, click the 2. Stop Capture button.


Click the  3. Save Capture  button. Save the .SAZ file to your desktop.


Open the generated SAZ with Fiddler Everywhere to continue the debugging or email the .SAZ file from your desktop to your debugging buddy.
