suffix-byte-range-spec = "-" suffix-length suffix-length = 1*DIGIT use servlet pdf 417 integration tocompose barcode pdf417 in java British Royal Mail 4-State Customer Barcode A suffix-byte-range-spec is j2se PDF-417 2d barcode used to specify the suffix of the entity-body, of a length given by the suffix-length value. (That is, this form specifies the last N bytes of an entity-body.) If the entity is shorter than the specified suffix-length, the entire entity-body is used.

. Hypertext Transfer Protocol: HTTP/1.1. If a syntactically valid byt Java PDF417 e-range-set includes at least one byte-range-spec whose first-byte-pos is less than the current length of the entity-body, or at least one suffixbyte-range-spec with a non-zero suffix-length, then the byte-range-set is satisfiable. Otherwise, the byte-range-set is unsatisfiable. If the byte-range-set is unsatisfiable, the server SHOULD return a response with a status of 416 (Requested range not satisfiable).

Otherwise, the server SHOULD return a response with a status of 206 (Partial Content) containing the satisfiable ranges of the entity-body. Examples of byte-ranges-specifier values (assuming an entity-body of length 10000): The first 500 bytes (byte offsets 0-499, inclusive): bytes=0-499 The second 500 bytes (byte offsets 500-999, inclusive): bytes=500-999 The final 500 bytes (byte offsets 9500-9999, inclusive): bytes=-500 Or bytes=9500 The first and last bytes only (bytes 0 and 9999): bytes=0-0,-1 Several legal but not canonical specifications of the second 500 bytes (byte offsets 500-999, inclusive):. bytes=500-600,601-999 bytes= 500-700,601-999. 14.35.2 Range Retrieval Requ servlet PDF417 ests HTTP retrieval requests using conditional or unconditional GET methods MAY request one or more subranges of the entity, instead of the entire entity, using the Range request header, which applies to the entity returned as the result of the request:.

Range = "Range" ":" ranges-specifier A server MAY ignore the Rang pdf417 2d barcode for Java e header. However, HTTP/1.1 origin servers and intermediate caches ought to support byte ranges when possible, since Range supports efficient recovery from partially failed transfers and supports efficient partial retrieval of large entities.

If the server supports the Range header and the specified range or ranges are appropriate for the entity: The presence of a Range header in an unconditional GET modifies what is returned if the GET is otherwise successful. In other words, the response carries a status code of 206 (Partial Content) instead of 200 (OK)..

Appendix C Hypertext Trans fer Protocol: HTTP/1.1. The presence of a Range he javabean pdf417 ader in a conditional GET (a request using one or both of If-Modified-Since and If-None-Match, or one or both of IfUnmodified-Since and If-Match) modifies what is returned if the GET is otherwise successful and the condition is true. It does not affect the 304 (Not Modified) response returned if the conditional is false. In some cases, it might be more appropriate to use the If-Range header (see section 14.

27) in addition to the Range header. If a proxy that supports ranges receives a Range request, forwards the request to an inbound server, and receives an entire entity in reply, it SHOULD only return the requested range to its client. It SHOULD store the entire received response in its cache if that is consistent with its cache allocation policies.

. 14.36 Referer The Referer [sic] request-he awt barcode pdf417 ader field allows the client to specify, for the server s benefit, the address (URI) of the resource from which the Request-URI was obtained (the referrer, although the header field is misspelled.) The Referer request-header allows a server to generate lists of back-links to resources for interest, logging, optimized caching, etc. It also allows obsolete or mistyped links to be traced for maintenance.

The Referer field MUST NOT be sent if the Request-URI was obtained from a source that does not have its own URI, such as input from the user keyboard.. Referer = "Referer" ":" ( absoluteURI relativeURI ). Example:. Referer: If the field value is a rela tive URI, it SHOULD be interpreted relative to the Request-URI. The URI MUST NOT include a fragment. See section 15.
