+and compare it against the given stat object.
+
+
+
Parameters

+
+
- + req: HTTP request message object + + +
- + stat: A file.stat object + + +
Return values:
+-
+
+
- Boolean indicating whether the precondition is ok + +
- Alternative status code if the precondition failed + +
- Table containing extra HTTP headers if the precondition failed + +
+
+

+
+
+14.27 / If-Range
+
+The If-Range header is currently not implemented due to the lack of general
