Hi, It is generating " WARNING: Can't acquire lockfile '/usr/local/trafficserver/var/trafficserver/server.lock' (Lock file held by process ID 17952) " warning when I execute " sudo $PREFIX/bin/traffic_server -T debug-hello" this. Also tell me how can we categories http header request user agents. Since ATS receives request from different user agents and keeps a copy in cache for each UA, that mean for a single url I have multiple copies on the basis of user agents. Kindly tell me is there any mechanism to categories all UAs with a single one?
