Configuring Windows Media Player to use a proxy
In explicit proxy caching, the user’s media player must be configured to use Media-IXT as a proxy.
With Windows Media Player, different versions on different operating systems have different possibilities:
• Windows Media Player 6 for PC can be configured to use a proxy for HTTP
• Windows Media Player 7 for PC can be configured to use a proxy for HTTP and for MMS
• Windows Media Player 7 for Macintosh OS is not documented here
The alternatives for Windows Media Player on PC are explained in turn.
To configure Windows Media Player 6 to use a proxy for HTTP:
1. From Windows Media Player’s View menu, select Options.
2. Click Advanced.
3. Highlight Streaming Media (Windows Media).
4. Click Change.
