All, I'm attempting to configure squid to proxy my requests to a Web Service. I can access via a GET request in my browser but attempting to submit a request via Java that has been configured to use squid as my proxy: Execute:Java13CommandLauncher: Executing '/usr/lib/jvm/java-1.5.0-sun-1.5.0.18/jre/bin/java' with arguments: '-Djava.endorsed.dirs=extensions/endorsed' '-Dhttp.proxyPort=3128' '-Dhttp.proxyHost=127.0.0.1' 1266334195.708 1 127.0.0.1 TCP_DENIED/411 1949 POST http://cadsr-dataservice.nci.nih.gov:80/wsrf/services/cagrid/CaDSRDataService - NONE/- text/html Thinking that I had messed up my config, I returned to the out of the box squid.conf and I get the same error. Thoughts?
