| *14.17 Content-Type |
| * |
| * The Content-Type entity-header field indicates the media type of the |
| * entity-body sent to the recipient or, in the case of the HEAD method, |
| * the media type that would have been sent had the request been a GET. |
| * |
| * Content-Type = "Content-Type" ":" media-type |
| * |
| * Media types are defined in section 3.7. An example of the field is |
| * |
| * Content-Type: text/html; charset=ISO-8859-4 |
| * |
| * Further discussion of methods for identifying the media type of an |
| * entity is provided in section 7.2.1. |
