Timeout

   TimeOut = "Timeout" ":" 1#TimeType 
   TimeType = ("Second-" DAVTimeOutVal | "Infinite")  
              ; No LWS allowed within TimeType
   DAVTimeOutVal = 1*DIGIT

Clients MAY include Timeout request headers in their LOCK requests. However, the server is not required to honor or even consider these requests. Clients MUST NOT submit a Timeout request header with any method other than a LOCK method.

The "Second" TimeType specifies the number of seconds that will elapse between granting of the lock at the server, and the automatic removal of the lock. The timeout value for TimeType "Second" MUST NOT be greater than 2^32-1.

See Section 6.6 for a description of lock timeout behavior.
