Redirecting to a pool

I m sorry, the actual iRule which I m using is as below

 

 

when HTTP_REQUEST priority 10 {

 

switch -glob [HTTP::path] {

 

"/123*" { pool hello_9090_Pool }

 

}

 

}

 

e.g.

[root@ve10:Active] config  b virtual bar list
virtual bar {
   destination 172.28.19.79:http
   ip protocol tcp
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
   if {[string tolower [HTTP::uri]] starts_with "/123/"} {
      HTTP::redirect "http://[string map {www hello} [HTTP::host]]:9090[HTTP::uri]"
   }
}
}

[root@ve10:Active] config  curl -I http://www.XYZ.com/123/something
HTTP/1.0 302 Found
Location: http://hello.XYZ.com:9090/123/something
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

Are you looking to "redirect", or simply use the pool members which listen on a different port(9090)? If you do not want to redirect, but use the pool you have in your iRule, you may have to correctly set the Host header on all requests to hello.XYZ.com or configure the pool members to listen for requests for www.XYZ.com in your example. This would be the case if you are taking requests for www.XYZ.com and load balancing them to a pool of servers that are accepting connections only for Host header hello.XYZ.com

sorry i forgot to remove /123 in redirection. this is the revised one.

[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
   if {[string tolower [HTTP::uri]] starts_with "/123/"} {
      HTTP::redirect "http://[string map {www hello} [HTTP::host]]:9090[string map {/123/ /} [HTTP::uri]]"
   }
}
}

[root@ve10:Active] config  curl -I http://www.XYZ.com/123/something
HTTP/1.0 302 Found
Location: http://hello.XYZ.com:9090/something
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

and this is an example based on Eric's suggestion.

[root@ve10:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.79:http
   ip protocol tcp
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
   if {[string tolower [HTTP::uri]] starts_with "/123/"} {
      HTTP::header replace Host "[string map {www hello} [HTTP::host]]:9090"
      HTTP::uri [string map {/123/ /} [HTTP::uri]]
      pool hello_9090_Pool
   }
}
}
[root@ve10:Active] config  b pool hello_9090_Pool list
pool hello_9090_Pool {
   members 200.200.200.101:websm {}
}

[root@ve10:Active] config  ssldump -Aed -nni 0.0 port 80 or port 9090
