Description

Hi, with the latest release of Proxyman it seems to be intercepting more traffic than previous versions when it comes to doing a hot reload of a React Native app. The bundle of the app we're developing is quite large and we're seeing that Proxyman is consuming roughly 3GB of memory per reload of the app meaning we can only run Proxyman for a short amount of time before the OS memory is exhausted. The traffic is being generated from a websocket URL like ws://localhost:9090/ - is there a recent change to Proxyman that could be causing this? This happens regardless of whether SSL proxying is turned on or not.

Steps to Reproduce

Create a react native project (we are using 68.5 but it shouldn't matter which version is used I think)
Use an iOS simulator, run the app and do repeated hot reloading of the bundle (can be triggered by CMD+D and selecting reload in the debug menu)
Observe that the memory footprint of Proxyman grows substantially with each reload

Current Behavior

Memory usage increases dramatically with each reload

Expected Behavior

There should be an ability for Proxyman to ignore this traffic as per previous versions

Environment

App version: Proxyman 4.9.1
macOS version: macOS Ventura 13.4.1

@steemcb-phorest look like there is an infinite loop when making a WS Request to port 9090, which is a port that Proxyman is listening to. Let me investigate it and fix it 👍

@steemcb-phorest can you try this Beta build: https://download.proxyman.io/beta/Proxyman_4.9.1_Fix_infinite_loop_react_native.dmg

It detects the infinite loop (ws://localhost:9090) and breaks the loop. Let me know if it fixes your issue 👍

Hi @NghiaTranUIT thanks so much for looking at this so quickly, the fix seems to work! Do you know when this could be released in an official build?

Maybe 1-2 weeks. You can safely use the Beta build without any problems.
