Remarks

Use this Node to store frequently accessed or immutable data. Separate cache instances are managed per Site and each site may store a maximum of 50MB of data.

The Cacher backs onto persisted storage and permits data to be shared across Workflow instances and Workflows. If the content in a cache is being built up progressively (for example by using the Append Action), take care to avoid race conditions where another Workflow multiple workflows may be accessing the same cache content simultaneously.

To progressively build up a string in memory (ie. without persistence), use String Builder.
