My isa is configure to cache mode only. all my clients are connected to the internet throw the isa on port 8080. On my client WS I am able to view gif on https page only if my internet explorer (6.0)is configure to "save encrypted pages to disk" If i am work without proxy i am able to see the gif anyhow. My isa is configure to listen to ssl on 443 port and i don't have any filter . any idea ?
