Here  is the patch I have been using myself. I am embarrassed to say that I 
was the 2nd person to ask and I forgot to post the patch for inclusion. I 
don;t have a version for 2.5/6 but this works for 2.4 (based on 
2.4.22-pre10). Tom, I am not sure this is exactly what yoou wanted when we 
initially talked about it so let me know if you would like a better method.


Thanks
Brian
