I have setup like below :-
end user >> LinuxProxy(3.1.10) >> External Proxy(3.4)>> Internet
- when we configure external proxy ip in end user's IE, all HTTP & HTTPS site work properly.
- when we configure Linux proxy ip in end user's IE, HTTP works fine but none of the HTTPS site open.
- when we access https site from LinuxProxy, below logs are appearing in access.log
TCP_MISS/503 0 CONNECT sitename:443 username@xxxxxxxxxxxx DIRECT / - -
TCP_MISS/200 23456 GET http://www.anysite.com username@xxxxxxxxxxxx DEFAULT_PARENT/10.10.x.x text/html
what I making out from log is ( I might be wrong) - HTTPS request are going directly instead .
attached is my Linux Proxy config-
