# Use DREADDDATA

The DIH accepts the `DREADDDATA` indexing action, which allows you to send data over a socket to the DIH for indexing. This action requires a POST request method. Use the following action syntax:

    http://DIHhost:IndexPort/DREADDDATA?optionalParamsData#DREENDDATAkillDuplicatesOption\n\n

When you send this action to the DIH instead of to an IDOL Server, note:

- `DIHhost` and `IndexPort` are the host and index port of the DIH, not of any of its child IDOL Servers.
- In mirror mode, DIH sends the data to every child IDOL server for indexing. In simple non-mirror mode, the DIH decides which IDOL server indexes the data, but all IDOL servers receive all actions. Use reference-based indexing or `DistributeSendMinimal` to further reduce the amount of traffic and IDOL server load by allowing the DIH to distribute index data and index actions.
