Bypassing a VIP based on destination address
Hi All,
Our LTM is configured with a PROXY_VIP and WEBMAIL_VIP which load balances proxy and webmail traffic for schools. Schools use the PROXY_VIP to access HTTP/HTTPS web sites and the IP address of the PROXY_VIP is hard coded in the student's browser.
So if schools need access to http://webmail.com, their request first gets served by the PROXY_VIP which load balances the request to a real proxy server and then the proxy server goes and fetches the webmail page which in turn gets load balanced by the WEBMAIL_VIP.
Can the LTM do the following:
1/ If the request is from a school IP address and the destination address is http://webmail.com, can we bypass the PROXY_VIP and redirect the request to the WEBMAIL_VIP.
2/ If 1 is not possible, once the request hits the PROXY_VIP and the destination address is http://webmail.com , can we use HTTP Redirection to redirect the request to the WEBMAIL_VIP but PRESERVE the School's IP address as the source IP rather than it being the IP address of the proxy server???
The reason for doing this is so that we can maintain source address persistence like so: school IP -> webmail machine rather than proxy server IP -> webmail machine.
Thanks.
Andy
