Describe the bug

https://www.ory.sh/docs/guides/protect-page-login/expressjs#require-login-to-access-the-home-page

.toSession seems to want to make a call to /.ory/.../whoami through the proxy. However i think axios wants to make this call at localhost port 80, leading to the following error

[0] Error: connect ECONNREFUSED ::1:80
[0]     at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1161:16) {
[0]   errno: -61,
[0]   code: 'ECONNREFUSED',
[0]   syscall: 'connect',
[0]   address: '::1',
[0]   port: 80,
[0]   config: {
[0]     url: '/.ory/sessions/whoami',
[0]     method: 'get',
[0]     headers: {

So we need to tell axios it should match the port we used when we started the proxy

"dev:proxy": "ory proxy --no-jwt --port 8000 http://localhost:8001/"

some solutions at the doc level

1. insist we pass a proxy to axios in development environments

.toSession(undefined, req.header('cookie'), {
    proxy: {
        host: 'localhost',
        port: 8000
    }
})

2. in development make sure we pass the full base path inclusive of port

const ory = new orySDK.V0alpha2Api(
    new orySDK.Configuration(
        // @ts-ignore
        {basePath: 'http://localhost:8000/.ory',
            baseOptions: {
                withCredentials: true
            }
        }
    )
)

These both work and i am also wondering

1. if there is a way to detect if we are proxying and on what port so this could be done automatically somehow
2. perhaps having this as an envar like the sdk url

Reproducing the bug

1. follow example on https://www.ory.sh/docs/guides/protect-page-login/expressjs
2. register a user
3. observe redirect loop once user registered due to failing whoami request
