Vercel Edge Middleware A/B Split Test Edge Runtime

In production marketing experiments, Vercel Edge Middleware inspects client cookie apex_bucket or geographically routes 33% of visitors to /, /v2, and /v3 with zero client-side layout shift.

import { NextResponse } from 'next/server'; import type { NextRequest } from 'next/server'; export function middleware(req: NextRequest) { // Read existing experiment cookie let bucket = req.cookies.get('apex_landing_variant')?.value; if (!bucket) { // Even 33% tri-split distribution across models const rand = Math.random(); bucket = rand < 0.33 ? 'v1' : rand < 0.66 ? 'v2' : 'v3'; } // Rewrite at the Vercel Edge without changing visible URL const res = NextResponse.rewrite(new URL(bucket === 'v1' ? '/' : `/${bucket}`, req.url)); res.cookies.set('apex_landing_variant', bucket, { maxAge: 2592000 }); return res; }
