<br>Thanks Per! Looking at <a href="http://varnish-cache.org/docs/trunk/reference/varnishd.html">http://varnish-cache.org/docs/trunk/reference/varnishd.html</a>; it seems I just need to add this in /etc/sysconfig/varnish:<br>

<br>Not sure what I'm missing here; but it seems like Varnish is returning HTTP 400 when I have an HTTP request with over 28 headers. Is this a configuration limit?<br></blockquote><div><br></div><div><br></div></div>
<div>
Yes. From varnishd(1), parameters:</div><div><br></div><span style="font-family: sans-serif; font-size: 16px; color: rgb(34, 34, 34);"><dt>http_headers</dt><dd style="margin-top: 3px; margin-bottom: 10px; margin-left: 30px; text-align: justify; line-height: 20px;">
