/**
|
|
* @vitest-environment node
|
|
*
|
|
* Next copies the body of every request proxy.ts runs for, up to
|
|
* proxyClientMaxBodySize, before the route sees it. That limit stays at the
|
|
* 10 MB default; the upload routes that need more are left out of the
|
|
* proxy's matcher. The matcher is read from proxy.ts the way `next build`
|
|
* reads it (static extraction), and a path counts as proxied the way Next's
|
|
* router decides it: when the raw or the decoded path matches.
