@DrDaveD but I am still lost this header `Cache-control: max-age` who is responsible for setting it up the client (the curl) or the (xrootd http server). I tried this without much luck: ```console efajardo@uaf-7 ~$http_proxy="http://cvmfs-1.t2.ucsd.edu:3128" curl -H "Cache-Control: max-age=86400" -v http://stashcache.t2.ucsd.edu:8000/user/dweitzel/public/blast/queries/query1 -O % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0* About to connect() to proxy cvmfs-1.t2.ucsd.edu port 3128 (#0) * Trying 169.228.130.85... * Connected to cvmfs-1.t2.ucsd.edu (169.228.130.85) port 3128 (#0) > GET http://stashcache.t2.ucsd.edu:8000/user/dweitzel/public/blast/queries/query1 HTTP/1.1 > User-Agent: curl/7.29.0 > Host: stashcache.t2.ucsd.edu:8000 > Accept: */* > Proxy-Connection: Keep-Alive > Cache-Control: max-age=86400 > < HTTP/1.1 200 OK < Content-Length: 103 < Date: Tue, 22 Oct 2019 16:54:31 GMT < X-Cache: MISS from cvmfs-1.t2.ucsd.edu < Via: 1.1 cvmfs-1.t2.ucsd.edu (squid/frontier-squid-4.4-2.1.osg34.el7) < Connection: keep-alive < { [data not shown] 100 103 100 103 0 0 10200 0 --:--:-- --:--:-- --:--:-- 11444 * Connection #0 to host cvmfs-1.t2.ucsd.edu left intact``` -- You are receiving this because you are subscribed to this thread.
