Let's imagine that loading the model can **take quite some time**, because it has to read a lot of **data from disk**. So you don't want to do it for every request.

            File file = null;
            try {
                file = new File(new URI(filePath));
            } catch (final URISyntaxException e) {
                logger.warn("Could not parse url: " + filePath, e);
            }

            if (file == null) {
                responseData.setHttpStatusCode(Constants.NOT_FOUND_STATUS_CODE);
                responseData.setCharSet(charset);

As seen in [Return a Response directly](response-directly.md){.internal-link target=_blank}, you can also override the response directly in your *path operation*, by returning it.

The same example from above, returning an `HTMLResponse`, could look like:
