I am sorry, but I am very confused here. no-cache is an attribute of
response. Why should I check it in req?

Anyway, this should not be so complicated. My simple requirement is that I
don't want varnish to cache my esi URL. Why can't I simply set something in
the response headers which tells varnish not to store it in cache.

I can write specific statements in varnish for that particular url, but I
don't want to do that as there will be more such urls with time. This logic
should be handled in my code, not in varnish.

&gt; So, what would be the best way to tell Varnish that I don&#39;t want to cache \
an<br> &gt; ESI fragment?<br>
<br>
</div>In your case, something like this on vcl_recv:<br>
<br>
if (req.http.cache-control ~ &quot;no&quot;) { return (pass); }<br>
<br>
If you have other pages that returns the http header cache-control:<br>
no, you have to be more specific at the if statement (req.url or<br>
something like that).<br>
