Esta interacción entre el cliente y el servidor para establecer la conexión TLS se llama **handshake TLS**.

   *       are files or sockets. This performs zero copies - the bytes never enter userspace.
   *   <li>Use mmap(2) or equivalent. Requires that either the input channel or the output channel
   *       have file descriptors. Bytes are copied from the file into a kernel buffer, then directly

### Create the **FastAPI** Code { #create-the-fastapi-code }

* Create an `app` directory and enter it.
* Create an empty file `__init__.py`.
* Create a `main.py` file with:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")

        for (final Entry<String, Map<String, CacheEntry<DfsReferralDataInternal>>> entry : domains.entrySet()) {

            for (final Entry<String, CacheEntry<DfsReferralDataInternal>> entry2 : entry.getValue().entrySet()) {
                log.trace("  Root " + entry2.getKey());
