Issue: Unable to execute tests in iOS 18 devices using Device-Farm-Plugin

We recently encountered issues when trying to use the Appium Device Farm plugin with iOS 18 devices. After investigating the logs, we identified several key points:

1. The Appium server was successfully initialized with the Device Farm plugin enabled.
2. The plugin detected available iOS simulators on the system.
3. However, when attempting to create a new session, the request was not properly routed to the Device Farm plugin.

Root Cause

The root cause appears to be related to how non-standard HTTP requests were being handled by the Appium server. Specifically:

• Requests to /session and /session/{sessionId}/timeouts were not being proxied to the Device Farm plugin.
• These requests resulted in 404 errors, indicating that the Appium server did not recognize them as valid routes.

[HTTP] --> POST /session {"capabilities":{"firstMatch":[{"appium:udid":"000000-1111111111","appium:newCommandTimeout":300,"appium:clearSystemFiles":true,"appium:webkitResponseTimeout":180000,"appium:autoAcceptAlerts":false,"appium:deviceName":"iPhone15Pro","appium:maxTypingFrequency":5,"platformName":"IOS","appium:automationName":"XCuiTest","appium:fullReset":false,"appium:app":"/Users/mukundhan.k/IdeaProjects/TestProject/TestApp.ipa","appium:usePrebuiltWDA":true}]}}
[device-farm-main] Received non-webdriver request with url /session. So, not proxying it to downstream.
[HTTP] No route found for /session
[HTTP] <-- POST /session 404 1 ms - 211
