Uh, don't bother. It'd be better off if it was rewritten from scratch.
The Apache proxy module has numerous race conditions and hasn't ever been

The JAWS papers at <http://www.cs.wustl.edu/~jxh/research/research.html>
especially this one:
<http://www.cs.wustl.edu/~jxh/research/papers/infocom98-jaws.ps.gz>
go over some nice analysis of the various models.
