# Class: com.pnfsoftware.jeb.util.net.Net

A network object used to download from and upload to http/https URLs, with socks and http proxy support.

## Constructor: Net

Description: Create a standard Net object, using global proxy settings set using [#setGlobalProxyInformation(NetProxyInfo)](#setGlobalProxyInformation(NetProxyInfo)). The user\-agent is set to "PNF Software UP"; the timeouts are set to 30 seconds for connect, 120 seconds for read, 60 seconds for write; redirects are followed.
