## Overview

The `web.config` file (`C:\Program Files (x86)\UiPath\Orchestrator`) holds settings used by the IIS, which are contained in the `<system.webServer>` element.

Learn [here](https://docs.microsoft.com/en-us/iis/configuration/system.webserver/) about `<system.webServer>`

Changing `web.config` automatically restarts the IIS.

### System.webServer

#### HTTP Compression

The element below enables the compression of dynamic content, respectively large downloadable `.csv` reports, in Orchestrator. By default, this feature is enabled

set to `true`. To disable it change the value of the `enabled` attribute to `false`.

```
<httpCompression>
  <dynamicTypes>
    <remove mimeType="text/csv" />
    <add mimeType="text/csv" enabled="true" />
  </dynamicTypes>
</httpCompression>
```
