virtualhost not picking up for non port 80

[Michael Ni <michaelcni@xxxxxxxxx>]

I'm having difficulty on windows XP getting a virtualhost to work with non port 80.
it works when i use port 80 in the virtualhost but doesn't work with other ports.  
i have turned off my firewall, although this is private ip, shouldn't matter
i have tried ports 8080, 8888, 8000, and now with 8886.
when it doesn't match my virtualhost, it will redirect to the main configuration servername automatically
if i turn off the all other "listen" and only keep "listen 8886", i will just be unable to connect
i have searched all over the internet but i can't find the solution.

hope someone can help.

the following is my config

------------------------------------
192.168.0.10    www.foobar.com

HTTPD.CONF
