Hi Amos, We've got response from Cisco team and they've agreed that destination IP gets changed when request passes through Cisco ISG. They are taking reference for configuration from this doc http://www.cisco.com/c/en/us/td/docs/ios/isg/configuration/guide/15_0s/isg_15_0s_book/isg_l4_redirect.html#wp1055689 Now they are very adamant that ISG l4 redirection works only this way. They are asking us to configure squid in a manner to retrieve destination host from http request. I am not aware if its possible or not. Any suggestions.?
