By default, proxy() ignores the Connection header to prevent Hop-by-Hop Header Injection attacks. You can enable strict RFC 9110 compliance with the strictConnectionProcessing option:
// Default behavior (recommended for untrusted clients)
app.get('/proxy/:path', (c) => {
return proxy(`http://${originServer}/${c.req.param('path')}`, c.req)
})
// Strict RFC 9110 compliance (use only in trusted environments)
app.get('/internal-proxy/:path', (c) => {
return proxy(`http://${internalServer}/${c.req.param('path')}`, {
...c.req,
strictConnectionProcessing: true,
})
})
