Virtual sites problem

[Pawel Tobis]

Wget does not retrieve pages located on virtual sites. For example, when I
want to download page from address http://www.fwbuilder.com/ which is a
virtual site on sourceforge.net, wget tries to download file
http://www.fwbuilder.com/index.html which does not exist.

I couldn't find any suitable option to turn that off
Please, give some workaround or advice for my problem.

I'm using GNU Wget 1.6 compiled on SunOS 5.7
