Server-Side Fix for App Store Links in In-App Browsers (Instagram/TikTok)

This post addresses a common issue where links to the App Store or Play Store do not function correctly when opened within in-app browsers like those on Instagram and TikTok. The author explains that client-side redirects are blocked by these webviews. The solution presented is a server-side 302 redirect, which the in-app browser will honor. A Cloudflare Worker example is provided to implement this fix, demonstrating how to dynamically redirect based on the User-Agent to either the Google Play Store or the Apple App Store.
