[Wordpress]homepage not purging

[Everton Blair]

Hi

I've just started using Varnish with Wordpress/W3TC, and all is ok, apart
from my homepage not purging when an update is made e.g. a new post.  I
think this might be because my homepage is using a static page
www.windows7news.com/magazine-homepage/ as it's homepage and is doing some
magic within Wordpress to show this page when the page
www.windows7news.com/is requested i.e. the server doesn't know that
www.windows7news.com/magazine-homepage/ needs purging.

I seem to have temporariliy managed to fix this by adding:

sub vcl_recv {
       if (req.url ~ "^/") {
               return(pass);
            }
}

But this means my most trafficked page isn't getting cached.  Is there
anyway to tell Varnish to always purge the homepage if there's a change?

Thanks in advance for any help.

My full VCL is below.  If anyone has any Wordpress specific changes they'd
like to share then please send them my way!

Regards

EB
