SYMPTOMS

Consider the following scenario:
  • In Windows Media Player, you enable the Use proxy settings of the Web browser option. (This is the default setting.)
  • Your installation of Windows Internet Explorer uses a proxy server to access certain types of URLs.
In this scenario, Windows Media Player does not use a proxy server as expected to access the same types of URLs. Therefore, Windows Media Player cannot load the content from these types of URLs.

For example, in Internet Explorer, you add *.server to the Exceptions list in the Proxy Settings dialog box. However, Windows Media Player may unexpectedly bypass Web sites whose URLs contain the following:
*.server*
*.server.*
When Internet Explorer accesses these URLs, it uses the proxy server as expected.

CAUSE

This issue occurs because of an error in Windows Media Player. After you enable the Use proxy settings of the Web browser option, Windows Media Player uses the proxy settings that are configured in the Web browser. However, Windows Media Player uses a unique algorithm to parse the Exceptions list of the Web browser.
