[Bug]: Cannot send secure cookie over unencrypted connection.

[yorinasub17]

Problem description

I'm getting the following TypeError from deno deploy when trying to set a secure cookie via the oak framework:

error: TypeError: Cannot send secure cookie over unencrypted connection.
    at SecureCookieMap.set (https://deno.land/std@0.200.0/http/cookie_map.ts:742:13)
    at file:///src/main.ts:7:21
    at dispatch (https://deno.land/x/oak@v12.6.1/middleware.ts:80:13)
    at composedMiddleware (https://deno.land/x/oak@v12.6.1/middleware.ts:83:12)
    at Application.#handleRequest (https://deno.land/x/oak@v12.6.1/application.ts:470:32)
    at Application.listen (https://deno.land/x/oak@v12.6.1/application.ts:656:28)
    at eventLoopTick (ext:core/01_core.js:183:11)
    at async file:///src/main.ts:15:1

This doesn't make sense to me since the entrypoint URL on deno deploy is a secure connection.

A minimal reproducible example is available at https://github.com/yorinasub17/deno-deploy-cookie-issue (deployed as clear-cow-34).

Steps to reproduce

1. Deploy https://github.com/yorinasub17/deno-deploy-cookie-issue
2. Visit home route

Expected behavior

Expect success page with 204 status, without error.

Environment

No response

Possible solution

No response

Gah this is an issue with oak, not deno deploy. Will close and reopen in right place. Apologies for the toil!
