Hi Eliezer , I have configured as : http_port 8080 //for forward proxy https_port 3128 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=cert.crt key=cert.key options= https_port 3129 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=cert.crt key=cert.key options= but still 'protocol error' exists. and I tried http_port 8080 //for forward proxy http_port 3128 https_port 3129 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=cert.crt key=cert.key options= still the same 'protocol error'. Is it due to the self-signed certificate......? It should work when I access http://www.hotmail.com, but it doesn't. As I'm redirecting port 80 to 3128.
