14.28 If-Unmodified-Since

14.28 If-Unmodified-Since

The If-Unmodified-Since request-header field is used with a method to make it conditional. If the requested resource has not been modified since the time specified in this field, the server should perform the requested operation as if the If-Unmodified-Since header were not present.

If the requested variant has been modified since the specified time, the server MUST NOT perform the requested operation, and MUST return a 412 (Precondition Failed).

         If-Unmodified-Since = "If-Unmodified-Since" ":" HTTP-date

An example of the field is:

          If-Unmodified-Since: Sat, 29 Oct 1994 19:43:31 GMT

If the request normally (i.e., without the If-Unmodified-Since header) would result in anything other than a 2xx status, the If- Unmodified-Since header should be ignored.

If the specified date is invalid, the header is ignored.
