Tune the <code>max-execution-snapshots</code> attribute to place a cap on the number of history snapshots that can be taken per flow execution.
To disable snapshotting, set this value to 0. To enable an unlimited number of snapshots, set this value to -1.
<note>
<para>
History snapshots enable browser back button support.
When snapshotting is disabled pressing the browser back button will not work.
It will result in using an execution key that points to a snapshot that has not be recorded.
