Before setting `convert_underscores` to `False`, bear in mind that some HTTP proxies and servers disallow the usage of headers with underscores.

## Duplicate headers

It is possible to receive duplicate headers. That means, the same header with multiple values.

You can define those cases using a list in the type declaration.

You will receive all the values from the duplicate header as a Python `list`.

			advance, token, err := s.split(s.buf[s.start:s.end], s.err != nil)
			if err != nil {
				if err == ErrFinalToken {
					s.token = token
					s.done = true
					// When token is not nil, it means the scanning stops
					// with a trailing token, and thus the return value
					// should be true to indicate the existence of the token.
					return token != nil
				}
				s.setErr(err)
				return false
			}

 2. It attempts to retrieve a connection with that address from the **connection pool**.
 3. If it doesn't find a connection in the pool, it selects a **route** to attempt. This usually means making a DNS request to get the server's IP addresses. It then selects a TLS version and proxy server if necessary.

By the last <a href="https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools" class="external-link" target="_blank">Python Developer Survey</a>, that covers about 80% of the users.

It means that **FastAPI** was specifically tested with the editors used by 80% of the Python developers. And as most of the other editors tend to work similarly, all its benefits should work for virtually all editors.

// used rather than just deleting the webhook since we want to keep it around after changing the default so user can later

// old version and then later decides to switch back to the old revision again.

   * observe the new rate; only subsequent requests will.

   * <p>Note though that, since each request repays (by waiting, if necessary) the cost of the
   * <i>previous</i> request, this means that the very next request after an invocation to {@code
   * setRate} will not be affected by the new rate; it will pay the cost of the previous request,
   * which is in terms of the previous rate.

 * This leads to a second side effect in that any @Inject request for just ModelProcessor in

        users indicates that they really appreciate Guava's high power-to-weight ratio. It's
        important to us to keep Guava as easy to use and understand as we can. That means boiling
        features down to compact but powerful abstractions, and controlling feature bloat carefully.


        Guava's main yardstick for evaluating proposed features can be summed up as [utility times
