Hi, I am reading the message that says squid3 supports ESI(EDGE SIDE INCLUDES). Can you any one explain me the functionality of ESI..? Can we use this as alternate to ICAP. Here is my few requirements 1) I like to display a banner appear on client brwoser for each request. 2) When some body clicks on that banner. The IP address of the server it takes to has to be logged. Can any one suggest an idea on how we can do this. Regards, -Balu. __________________________________________________ Do You Yahoo!?
