When a web browser gets an HTTP response containing a text document rather than an HTML document, the browser switches off the HTML processing engine and shows the text document verbatim. An alternative approach would have been to assume the document is the body of an HTML document that is missing the html and body tags. Explain what would happen if the browser treated the text document as the body of an HTML document and renders the text document using this approach. Describe what you expect the browser to display if given a commonly used text document such as a text-only email or a C++ header file. List any differences from what is shown using the verbatim approach.
