The Mechanics of In-App Browser Sandbox Isolation
Instagram sandboxes all external links inside its internal web browser. This restricts cookies, which sign users out of Amazon, YouTube, and other websites. Bypassing this sandbox requires a deep routing script that detects the webview and forces the browser to call a native system intent.
Using Custom URL Schemes & Intent Headers
By writing dynamic response headers, MyLynq triggers a protocol transition (e.g. `intent://` on Android, `universal link` on iOS), forcing the system to bypass the Instagram shell and query target app packages directly. This launches the corresponding native application instantly, preserving user logins.
Frequently Asked Questions
No. The bypass is triggered completely server-side and uses native OS protocols. Visitors do not need to install anything.
