Hi~ I have a nginx webserver adding the static-etags module and a squid2.6.23 before the nginx. When I access to the nginx directly, I can see the ETag in response header and If-None-Match in the request header after refresh. But when I access to the squid, ETag header still exist,If-None-Match header disappeared! The squid.conf have most basic configuration items, nothing about cache. Why does this happen?
