Filename in log4net

Hi All,
i am doing a VB.NET windows application. In that i am using Log4Net for logging details. I am new to using Log4Net. The problem i am facing is i want to create the logfiles with same name each day. means today if a log file is created with name debug.log, tomorrow also it should create a new log file with same name with out any change in the previous file name. how can i do this ? My appender configuration looks like this ..

<appender name="RSLogFileAppenderDebug" type="log4net.Appender.RollingFileAppender">
<file value="C:\Log4NetExamples\debug.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<filter type="log4net.Filter.LevelRangeFilter">
<acceptOnMatch value="true" />
<levelMin value="DEBUG" />
<levelMax value="FATAL" />
</filter>
<maxSizeRollBackups value="1" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%newline%date [%thread] %-5level - %message" />
</layout>
</appender>

<appender name="RSLogFileAppenderFatal" type="log4net.Appender.RollingFileAppender">
<file value="C:\Log4NetExamples\Fatal.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<filter type="log4net.Filter.LevelRangeFilter">
<acceptOnMatch value="true" />
<levelMin value="FATAL" />
<levelMax value="FATAL" />
</filter>
<maxSizeRollBackups value="1" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%newline%date [%thread] %-5level - %message" />
</layout>
</appender>

<root>
<level value="ALL" />
<appender-ref ref="RSLogFileAppenderDebug" />
<appender-ref ref="RSLogFileAppenderFatal" />
</root>

How can i do this ?? do i need to make any change in the appender config ? can anybody help?
