There are two overloaded ClearPage methods. For the second overloaded method, the supported action conditionals include:

• IfModifiedSince
• IfUnmodifiedSince
• IfMatch
• IfNoneMatch
• if-sequence-number-lte
• if-sequence-number-lt
• if-sequence-number-eq

The following table describes the parameters:

Parameter	Description
ContainerName	The name of the container the blob is in.
BlobName	The name of the page blob.
StartPage	The zero-based index of the first page this action applies to.
PageCount	The number of pages this action applies to.
ActionConditional	Conditions that must be met for the action to be executed.
LeaseId	The lease ID, required if the blob is locked.

The method returns True if the action is successful, and False otherwise.
