		Title: `Non-canonical key in \'http.Header\' map`,
		Text: `Keys in \'http.Header\' maps are canonical, meaning they follow a specific
combination of uppercase and lowercase letters. Methods such as
\'http.Header.Add\' and \'http.Header.Del\' convert inputs into this canonical
form before manipulating the map.

When manipulating \'http.Header\' maps directly, as opposed to using the
provided methods, care should be taken to stick to canonical form in
order to avoid inconsistencies. The following piece of code
demonstrates one such inconsistency:

    h := http.Header{}
    h["etag"] = []string{"1234"}
    h.Add("etag", "5678")
    fmt.Println(h)

    // Output:
    // map[Etag:[5678] etag:[1234]]

The easiest way of obtaining the canonical form of a key is to use
\'http.CanonicalHeaderKey\'.`,
