%5C issue in url_rewrite_program

[Jeff Jensen <jjensen@xxxxxxxxxxx>]

Hello,
   What is the fix for %5C in the DOMAIN%5CUsername issue? I have
Squid 3.0.STABLE7 fully functional against Active Directory with Samba
3.2.3. In my Squid access.log I see DOMAIN\Username. When this is sent
to squidguard 1.2.0 via url_rewrire_program squidguard logs show
DOMAIN%5CUsername.

Thanks

P.S. I've searched the mailing list and googled much.
