Thanks for the pointer.  I'm using 1.3.26.1a, the released version
on Linux with Apache 1.3.27 (RedHat RPMs).

I think Christian may have added some code after the release of
1.3.26.1a, as his final comments in the bug report above are towards
the end of October and 1.3.26.1a was released Oct 1.  There aren't any
patches for 1.3.26.1a that seem to address this.  I suppose the only
method to get Christian's fixes is to pull directly from CVS.
Is this correct?

Thanks.
