# Proxy Servers

Overview Configuration

## Overview
You can configure settings for individual proxy servers on the External Connections tab, which you can then specify at the filter level (in the Connection and Connect To URL filters). When configured, the filter connects to the HTTP proxy server, which in turn routes the message on to the destination server named in the request URI. For more details, see the Connection and Connect To URL topics. These proxy server settings are different from the global proxy settings in the Preferences dialog in the Policy Studio, which apply only when downloading WSDL, XSD, and XSLT files from the Policy Studio. For more details, see the Policy Studio Preferences topic.
## Configuration
