I am tying to redirect a specific https request to somewhere else. I've been trying to use squid which worked for http, but it's unable to see https request. Is it even possible to do this as the request is already encrypted and squid can't even see it.
I've tried using squid with and without squirm without success. Checking squid logs, only http requests are logged and no https are logged, meaning https are not going through squid?
I've tried the trick here http://www.rahulpahade.com/content/squid-transparent-proxy-over-ssl-https. As soon as I enable the firewall settings, all requests to https are blocked. But if disable forwarding 443 to squid server without any changes to the squid config, it's working again.
Please help.
Thanks

Yes, you can perform this, but it isn't exactly trivial.
First, you need to establish a certificate authority that trusted by the client. Once oyu have done that, you can use the sslbump feature of Squid to perform the decryption (see http://wiki.squid-cache.org/Features/SslBump).
While you do not explain the context of what you want to do, it is probably worthwhile mentioning that if what you want to do is debug outgoing HTTPS connections coming from a windows machine, you can perform this in a much simpler way by using the Fiddler web debugger (http://www.fiddler2.com/fiddler2/)
