| /** |
| * Represents a parsed <l>Content-Length</l> HTTP request/response header. |
| * |
| * <p> |
| * The length of the response body in octets (8-bit bytes). |
| * |
| * <h5 class='figure'>Example</h5> |
| * <p class='bcode w800'> |
| * Content-Length: 348 |
| * </p> |
| * |
| * <h5 class='topic'>RFC2616 Specification</h5> |
| * |
| * The Content-Length entity-header field indicates the size of the entity-body, in decimal number of OCTETs, sent to |
| * the recipient or, in the case of the HEAD method, the size of the entity-body that would have been sent had the |
| * request been a GET. |
| * <p class='bcode w800'> |
| * Content-Length = "Content-Length" ":" 1*DIGIT |
| * </p> |
| * |
| * <p> |
| * An example is... |
| * <p class='bcode w800'> |
| * Content-Length: 3495 |
| * </p> |
| * |
| * <p> |
| * Applications SHOULD use this field to indicate the transfer-length of the message-body, unless this is prohibited by |
| * the rules in section 4.4. |
| * |
| * <p> |
| * Any Content-Length greater than or equal to zero is a valid value. |
| * Section 4.4 describes how to determine the length of a message-body if a Content-Length is not given. |
| * |
| * <p> |
| * Note that the meaning of this field is significantly different from the corresponding definition in MIME, where it is |
| * an optional field used within the "message/external-body" content-type. |
| * In HTTP, it SHOULD be sent whenever the message's length can be determined prior to being transferred, unless this is |
| * prohibited by the rules in section 4.4. |
| * |
| * <ul class='seealso'> |
