There is a **special** environment variable called **`PATH`** that is used by the operating systems (Linux, macOS, Windows) to find programs to run.

The value of the variable `PATH` is a long string that is made of directories separated by a colon `:` on Linux and macOS, and by a semicolon `;` on Windows.

For example, the `PATH` environment variable could look like this:

//// tab | Linux, macOS

mc admin trace --all --verbose myminio
```

Use the following command to generate a private key with RSA:

```sh
openssl genrsa -out private.key 2048
```

A response similar to this one should be displayed:

```
Generating RSA private key, 2048 bit long modulus
............................................+++
...........+++
e is 65537 (0x10001)
```

Alternatively, use the following command to generate a private RSA key protected by a password:

```sh

Start your application and go to <a href="http://127.0.0.1:8000/static/redoc.standalone.js" class="external-link" target="_blank">http://127.0.0.1:8000/static/redoc.standalone.js</a>.

You should see a very long JavaScript file for **ReDoc**.

It could start with something like:

Requests can be "Single Payload" or "Streamed".

Use the MinIO Grid for:

* Small, frequent requests with low latency requirements.
* Long-running requests with small/medium payloads.

Do *not* use the MinIO Grid for:

* Large payloads.

Only a single connection is ever made between two servers.

For example, imagine you have code that uses a database session in a dependency with `yield` only to verify a user, but the database session is never used again in the *path operation function*, only in the dependency, **and** the response takes a long time to be sent, like a `StreamingResponse` that sends data slowly, but for some reason doesn't use the database.
