Hello Meftahur Rahman , JSAM stands for Java Secure Application Manager. When we say Java, we are basically talking about Java Applets here. How does JSAM function? - Remember, there is already a SSL tunnel between the client and the IVE. - For example: If the IVE is configured for users to access bbc.com via JSAM, then when the client access the IVE and launch JSAM, the following happens: - JSAM will now immediately modify the computer "host file" and add the bbc.com is on 127.0.1.X loopback IP address. - JSAM also will do a backup of the "original host file" on the client machine. (You can see this when you go to C:\WINDOWS\system32\drivers\etc location after launching JSAM) - Now, when a user hits bbc.com, the computer will try to do name lookup and it will check the "host file" where, it has the entry saying, bbc.com needs to be reached through 127.0.1.X. - The browser sends the traffic to the JSAM java applet listening on this loopback IP and that traffic is forwarded / tunneled to the IVE using the inital SSL connection to the IVE which the client already has with the IVE over port 443. Hope the above helps you. Please mark this post as 'accepted solution' if this answers your question that way it might help others as well, a kudo would be a bonus thanks
