AEM Dispatcher Cache not working, Expires Header being added

[pradeep8910]

I am seeing an response header being added (Expires:Thu, 01 Jan 1970 00:00:00 GMT) in AEM publish for all the requests like clientlibs/page requests and images. This is preventing the responses to be cached from dispatcher and cdn.

I don't see this being set in code base or acs commons dispatcher configs being set

Hi @pradeep8910 
Please dispatcher and DCN settings as well.

Try accessing page with Author, Publish, dispatcher and CDN urls, to check from where the headers is appended.

Hi @pradeep8910 

Try Header unset Expires in dispatcher

<LocationMatch "^\/content\/dam.*\.(xml|css|eot|gif|ico|jpg|jpeg|js|png|svg|swf|ttf|woff|woff2|pdf|txt|mp4|mp3|ics)$">
       Header unset Cache-Control
       Header unset Expires
       Header always set Cache-Control "max-age=0"
       Header always set Surrogate-Control "max-age=0"
       Header set Age 0
    </LocationMatch>
