# PreserveDREADD

By default, the DIH converts incoming `DREADD` index actions, which contain a reference location of the file to index, to `DREADDDATA` index actions, which send the data directly. You can use the `PreserveDREADD` configuration parameter if you want DIH to forward the `DREADD` action directly.

In this case, all the child servers must be able to access the file system that contains the original IDX file, using the file path specified in the `DREADD` index action. This option can reduce network load, because DIH sends only the path to the IDX file, rather than streaming all the data.

NOTE: You can use this parameter only in simple mirror or non-mirror mode.
