[logback-user] Multiple log files to single archive

[David Roussel]

Tom,

If you create a ticket no one is going to do the work for you as I don't think anyone else needs this functionality. If you implement it by all means pleas contribute back. I'm not a commiter, just a user.

You could start by subclassing one of the existing rolling implementations and add in your extra logic. 

It does all seem to get complicated quickly. How do you configure the archive interval? A new tag in the confg? How do you match all the older files, but not the current one etc. 

What advantage do you think you are gaining from this scheme you are suggesting?

I guess the concept of rolling should be twofold - the log files roll independently of the archives and the archives roll every n archive rolls. The moment the archive rolls all logs should be archived.
