By adding metadata to your announcement file (the file with an .asx file name extension), you can provide information that will appear in the captioning area of Windows Media Player when users receive the content. You can also specify the location to which the Player sends client log information. All entries on this wizard page are optional.
When a player connects to a unicast stream, it submits log data back to the Windows Media server. By including a value for this property in your announcement file, the player submits two sets of log data: one to the Windows Media server and one to the Web server you specify in LogURL.
If you are announcing a multicast stream and have already specified the URL of a Web server on the Multicast Logging page, you can leave this property blank or specify an additional Web server. The URL of the Web server specified on the Multicast Logging page is saved to the multicast information file, while this URL is saved to the announcement file. If the same Web server address is specified on both pages, the log files will be submitted to the Web server twice.
<LOGURL HREF="http://web_server_name/log_folder_name/logging_page_name" />.
