https is using port 443. You must redirect port 443 traffic in order to pass https to web-proxy.
I already used this rule before I post this topic , i got msn and everything uses SSL down ...
Notice that if I made some settings at our clients or If i put proxy for explorer and passes through local .. surfing gets much better with it but if I left it at normal settings which is default port 80 it will only cache HTTP requests , another thing is do not forget that some pictures and exe files are being downloaded from HTTPS .
What do you think the best solution for HTTPS request and how can we forward it to cache ?
