# Using the Request Directly

Up to now, you have been declaring the parts of the request that you need with their types.

Taking data from:

* The path as parameters.
* Headers.
* Cookies.
* etc.

And by doing so, **FastAPI** is validating that data, converting it and generating documentation for your API automatically.

But there are situations where you might need to access the `Request` object directly.

 *  Fix: Don't crash when reading the empty `HEAD` response body if it specifies
    a `Content-Length`.
 *  Fix: Don't crash if the thread is interrupted while reading the public
    suffix database.
 *  Fix: Use relative resource path when loading the public suffix database.
    Loading the resource using a path relative to the class prevents conflicts

### Always `raise` in Dependencies with `yield` and `except`

If you catch an exception in a dependency with `yield`, unless you are raising another `HTTPException` or similar, you should re-raise the original exception.
