Jomashop UDL Server

A simplified, production-ready fork of fdocr/udl-server — stripped down to a single-purpose path-passthrough redirect server for Jomashop mobile app deep linking.

How it works

Bounces traffic through a separate domain so iOS Universal Links and Android App Links trigger correctly — even when users are browsing inside webviews (Instagram, TikTok, etc).
