I think `-IXGET` will cause *curl* to drop the body - ATS still serves it to you. Assuming ATS respects that Cache-Control header, then you should be fine to just send a `HEAD` request if you don't want the body. Although I think for objects that are less than up to (roughly) equal to the average object size, fetching the body will be a negligible additional cost as far as ATS is concerned.
If what you're trying to do is see what's stored in your cache, I shamelessly recommend the buggy-but-useful Superior Cache ANalyzer (SCAN) tool: https://github.com/comcast/superior-cache-analyzer ________________________________________ From: Miles Libbey <[email protected]> Sent: Wednesday, March 27, 2019 3:10 PM To: [email protected] Subject: [EXTERNAL] Re: check whether it will be a hit on trafficserver I do: curl -IXGET -H "Cache-Control: only-if-cached" "https://protect2.fireeye.com/url?k=918b742c9b1bbda4.918b5398-c36456a0d5da6c67&u=http://myurlhere"; The -IXGET makes it do a GET, but, drops the body. The Cache-Control: only-if-cached request header will have ATS respond with a 200 if the object is in cache, otherwise you get a 504 if not in cache. miles On Wed, Mar 27, 2019 at 11:49 AM Jason Yang <[email protected]> wrote: > > Hi community, > Is there anyway to check whether a request will be a hit or miss without > having trafficserver serving any content and not going to origin?
