Problem Description

First of all, thank you for your great work on this project!

I would like to suggest adding a filtering feature that allows users to exclude SSE (Server-Sent Events) request response times from request timing statistics.

Since SSE connections are long-lived by nature, their response durations tend to skew the overall request time metrics, making performance analysis less accurate—especially when mixed with standard HTTP requests.

A filter or toggle to exclude these would greatly improve the clarity and reliability of the data.

• SSE requests often stay open for minutes or longer.

• Including SSE durations in timing metrics can mislead users about actual response time behavior.

• It would help distinguish between real response delays vs. expected long-lived connections.

Feature Description

• Allow filtering based on Content-Type, request URL pattern, or response headers.

• Provide a toggle in the UI or a config option to exclude SSE requests from timing stats.

Additional Context

No response
