ATS not getting the updated file on origin server

[Fei Wan <wa...@yahoo.com>]

hi

I'm a newbie to ATS and just find out the ATS is not picking up the file updates on the origin server. I think ATS can detect file changes on origin server and refresh its cache if there's change. Is that right? Can you please let me know what're the things I might not set up properly? I'm running the ATS as a reverse proxy.

We have a file on the origin server as http://10.25.66.173/test.csv and following remap rules in the ATS remap.config:
map http://www.test.com/ http://10.25.66.173/

When I use the curl to get the file through ATS 
curl http://www.test.com/test.csv

I don't see ATS returning the updated file after I've made a change. The via codes from ATS are [uScHs f p eN:t cCHi p s ] . I also checked the access log on origin server and don't see ATS getting the file from origin.


Thanks,
Fei

Well, if its cached, we will serve it out of cache for as long as it is allowed to do so. What Expire or Cache-Control headers is the origin sending? Or are you using heuristics based on Last-Modified?
