ACE 4710 balance among URL

Question

I have ACE 4710 and I need configuration:
I have real web-server with  folders : /1/index.html, /2/index.html, /3/index.html
I need to  balance virtual service:
If I try to connect URL: http://server/index.html,  then ACE balance among
http://real_server/1/index.html,
http://real_server/2/index.html,
http://real_server/3/index.htm
How can I  configure ACE ?

Answer 1

ACE, can't modify the url.
But it can send redirect.
So you could build 3 redirect rservers, and have ACE loadbalance between them.
rserver redirect HTTP-REDIRECT1
  webhost-redirection http://real_server/1/index.html
  inservice
rserver redirect HTTP-REDIRECT2
   webhost-redirection http://real_server/2/index.html
   inservice
rserver redirect HTTP-REDIRECT3
   webhost-redirection http://real_server/3/index.html
   inservice
serverfarm redirect SF_REDIRECT
  rserver HTTP-REDIRECT1
    inservice
  rserver HTTP-REDIRECT2
    inservice
  rserver HTTP-REDIRECT3
    inservice
But even if it works, this does not sound good.
It seems like a design done by an application server person who does not know how network loadbalancers work.
It seems like all you need is stickyness, which you are trying to achieve by redirecting to /1 or /2 or /3.
But this can be done differently with cookies or by just doing stickyness on source ip address.
