Hi<div><br></div><div>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 <a href="http://www.windows7news.com/magazine-homepage/">www.windows7news.com/magazine-homepage/</a> as it's homepage and is doing some magic within Wordpress to show this page when the page <a href="http://www.windows7news.com/">www.windows7news.com/</a> is requested i.e. the server doesn't know that <a href="http://www.windows7news.com/magazine-homepage/">www.windows7news.com/magazine-homepage/</a> needs purging.</div>
<div><br></div><div>I seem to have temporariliy managed to fix this by adding:</div><div><br></div><div><div>sub vcl_recv {</div><div> <span class="Apple-tab-span" style="white-space:pre"> </span>if (req.url ~ "^/") {</div>
<div> return(pass);</div><div> }</div><div>}</div></div><div><br></div><div>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?</div>
<div><br></div><div>Thanks in advance for any help.</div><div><br></div><div>My full VCL is below. If anyone has any Wordpress specific changes they'd like to share then please send them my way!</div><div><br></div>
