I wasn't thinking so much about trying to have the layout inherited by the 
sub-appenders as much as apply the layout and actually format the data at the 
AsyncAppender level.  That way I only spend the resources formatting the data 
once (inside the AsyncAppender) instead of multiple times, once per 
sub-appender.

I realize the AsyncAppender does not support layouts, so I am looking for an 
alternative.  I ultimately want to format/convert the log message into a custom 
XML format, but only do it once and deliver it to multiple appenders.

Thanks,
Robbie

SocketAppender doesn't support a layout.

log4j doesn't support the concept of inherited layouts, so you'll have to 
specify it for each appender that needs one.

Subject: How to apply layout to AsyncAppender?

I have a scenario where I want to use multiple appenders for the same logger 
(FileAppender and SocketAppender for now).  Both appenders need to format the 
message using the same layout.  Instead of formatting the single message 
multiple times(in the FileAppender and in the SocketAppender), I was wanting to 
put both of these appenders under an AsyncAppender and apply the layout once in 
the AsyncAppender, then send the formatted message to my sub-appenders.  What 
is the best way to accomplish this?  From what I can tell the AsyncAppender 
does not support layouts.

Thanks,
Robbie
