RefreshLock
The RefreshLock operation refreshes the lock on a file.
POST /wopi/files/(file_id)
The RefreshLock operation refreshes the lock on a file by resetting its automatic expiration timer to 30 minutes. The refreshed lock must expire automatically after 30 minutes unless it's modified by a subsequent WOPI operation, such as Unlock or RefreshLock.
WOPI clients usually make a Lock request to lock a file prior to calling this operation. The WOPI client passes the lock ID established by that previous Lock operation in the X-WOPI-Lock request header.
If the file is currently locked and the X-WOPI-Lock value doesn't match the lock currently on the file, or if the file is unlocked, the host must do the following:
- Return a lock mismatch response (409 Conflict)
- Include an X-WOPI-Lock response header containing the value of the current lock on the file
In cases where the file is unlocked, the host must set X-WOPI-Lock to the empty string.
In cases where the file is locked by someone other than a WOPI client, hosts should still always include the current lock ID in the X-WOPI-Lock response header. However, if the current lock ID isn't representable as a WOPI lock (for example, it's longer than the maximum lock length), the X-WOPI-Lock response header should be set to the empty string or omitted completely.
For more general information regarding locks, see Lock.

Response headers
X-WOPI-Lock – A string value identifying the current lock on the file. This header must always be included when responding to the request with 409 Conflict. It should not be included when responding to the request with 200 OK.
X-WOPI-LockFailureReason – An optional string value indicating the cause of a lock failure. This header might be included when responding to the request with 409 Conflict. There's no standard for how this string is formatted, and it must only be used for logging purposes.
