irule To Redirect A Specific Network Going To a URL

It would look like the following to stick to your example with the string "media" contained in the hostname:

  }
  "*media*" {
       if { [class match [IP::client_addr] equals India_Host_Networks] } {
           HTTP::redirect " https://InhydNimble1.domain.com[HTTP::uri]"
           return
       } else {
           HTTP::redirect " https://media.domain.com[HTTP::uri]"
           return
       }
  }
  "*change*" {
     HTTP::redirect "http://site.domain.com/cm"
     return
  }
  "*empcon*" {
     HTTP::redirect "http://site.domain.com/?cmd=login"
     return
  }
  "*im*" {
     HTTP::redirect "https://site.domain.com/IntegratedLogin.asp"
     return
  }

By adding the

[HTTP::uri]

to the redirect you will preserve the initial path including variables. There is no need for an additional hostname evaluation. So I removed it. (It will be evaluated by the switch command and match the "*media*" as you are using the globbing option.)
