across another strategy. As far as I can tell, there is no good<br>
usecase for a non-zero s-maxage token outside your reverse-proxy. So<br>
now I just use the s-maxage token to tell Varnish how to cache and<br>
then strip it from the response headers (or reset to s-maxage=0) to<br>
avoid contaminating any forward proxies downstream.</blockquote><div><br></div><div>This seems logical to me. Are there any drawbacks to using Surrogate-Control?</div><div><br></div><div>--Michael</div></div>
