Please let me know if the “Partial Content Caching” is supported in Trafficserver 4.2.1 which I have downloaded from wget http://apache.petsads.us/trafficserver/trafficserver-4.2.1.tar.bz2.

I have found some links where the people were discussing about the partial content caching plugin https://cwiki.apache.org/confluence/display/TS/Partial+Object+Caching but I am not sure that whether it is there in the source code. Please let me know that and if it is not there in the source code please let me know where I can get it from.
