• webpack Version: ^4.40.2
• webpack-dev-server Version: 3.10.2

Code

I implemented a server function myself, go to compile webpack。

The following code is to proxy local mock requests

// app => devServer.app
app.use(`${prefix}/*`, localMockHandler(prefix, true)); 

function localMockHandler() {
    // return a middleware
    return () => {

    }
}

The get request is normal, but the post request will report 405。

but I use webpack-dev-server@3.8.1，It is good and normal。

Expected Behavior

post request can normal。

Actual Behavior

post request break，it tell me 405，post method not allowed。
