Thanks foo, that looks like it would work, but alas, I tested the perl
script this morning (should have done that yesterday), and it didn't
work...

I've decided to use wget to do this job, as you can give it an
argument of --header='' on the command line, which works perfectly.

Thanks for your reply too Stephane - I need the Host: header because
I'm working with LVS real servers inside the realserver network, so I
need to set the Host: header manually.

Cheers,
Guy.
