The server file is created when you install TortoiseSVN, Eclipse or command-line Subversion. Use the appropriate path from the installation folder to configure proxy settings:

• CLI Unix/Linux : /home/username/.subversion/servers
• CLI Windows (2k, XP): C:\Documents and Settings\username\Application Data\Subversion\servers
• CLI Windows (Vista/7): C:\Users\username\AppData\Roaming\Subversion\servers
• Eclipse: Window > Preferences > General > Network Connections
• IE (6/7): Tools > Options > Advanced Network > Connection Settings
• Firefox: Tools > Internet Options > Connections tab > LAN Settings
• TortoiseSVN: Windows Explorer > File > TortoiseSVN > Settings > Network (by default, TSVN uses system proxy settings)
