Stop capture after #### Sessions

Hi Telerik -

I need to capture a the web requests that go to an OAUTH token endpoint in order to troubleshoot a bug.

The app seldom refreshes tokens, and normally it works fine, but sometimes it gets stuck in a loop where it does it over and over and over.

Currently, if I use the "Keep #### Sessions" combobox, once it gets stuck, I get only the last #### sessions which is not what I want. I want the first ones so I can see what might have been different that caused it to get stuck in a loop.

Alternatively, I can keep all sessions but that crashes the PC because it uses all the RAM before I notice it when into the loop.

It would be great if, next to the "Keep: #### Sessions" drop down (or, perhaps, as a checkbox in the dropdown), there was an option to "Stop Capture after this limit."

Can you please add this feature?

Hi Tony,

Thank you for the suggestion. We appreciate the feedback and will consider this enhancement in future planning for the Fiddler Classic product.

As a side note, the Automated Save and Export feature in Fiddler Everywhere (the modern-day version of Fiddler) already covers your scenario. You can find more details in our documentation: Automated Save and Export.

When automated saving is configured, Fiddler Everywhere periodically saves the captured traffic to a .saz file, clears the Live Traffic grid, and continues capturing. This allows you to preserve the complete traffic history for later investigation while preventing the Live Traffic grid from accumulating a large number of sessions, which can increase memory and resource consumption.

I hope this workaround helps you collect the information needed to troubleshoot the token refresh loop without impacting system performance.
