NimbostratusUsing iRule for host header and uri routing (problem)
I have a virtual Server(F5) set up on an IP. I have two websites that share this IP and IIS is configured to handled host header hosting. I also run some java tomcat apps on one of the domains hosted so I need to route that to a different pool as well. So here is my config and maybe you all can help me
Virtaul server: Listens on 10.120.1.30 for www.host1.com, www.host2.com
www.host1.com gets routed to host1 pool
www.host2.com get routed to another pool
www.host1.com/pubservices-war gets hosted to tomcat pool
This all works correctly, but for some reason, I think something is being stripped out when host1 gets directed to the tomcat pool.
when HTTP_REQUEST {
switch [HTTP::host] {
www.host2.com { pool host2 }
www.host1.com {
if { [HTTP::uri] starts_with "/itunesu" } {
pool www.host1-Tomcat
} elseif { [HTTP::uri] starts_with "/iTunesu" } {
pool www.host1-Tomcat
} elseif { [HTTP::uri] starts_with "/iTunesU" } {
pool www.host1-Tomcat
} elseif { [HTTP::uri] starts_with "/pubservices-war" } {
pool www.host1-Tomcat
} elseif { [HTTP::uri] starts_with "/ref_form" } {
pool www.host1-Tomcat
} elseif { [HTTP::uri] starts_with "/ccv" } {
pool www.host1-Tomcat
}}
}
}
I believe by default all traffic goes to the default pool host1 as configured by the virtual server unless configured differently in the iRule.
Any thoughts?

Hi Stolivar,
Can you try this version of the iRule which explicitly selects a pool for all cases? Once you're done testing, you can disable or remove the debug logging.when CLIENT_ACCEPTED { Log debug to /var/log/ltm? 1=yes, 0=no. set switch_debug 1 Save the name of the VS default pool before the iRule could change it set default_pool [LB::server pool] } when HTTP_REQUEST { switch [string tolower [HTTP::host]] { www.host2.com { pool host2 if {$switch_debug}{log local0. "[IP::client_addr]:[TCP::client_port]: Using host2 pool for [HTTP::host][HTTP::uri]" return } www.host1.com { switch -glob [string tolower [HTTP::uri]] { "/itunesu*" - "/pubservices-war*" - "/ref_form*" - "/ccv*" { pool www.host1-Tomcat if {$switch_debug}{log local0. "[IP::client_addr]:[TCP::client_port]: Using www.host1-Tomcat pool for [HTTP::host][HTTP::uri]"} return } } } } If we are still in the iRule select the VS default pool pool $default_pool if {$switch_debug}{log local0. "[IP::client_addr]:[TCP::client_port]: Using $default_pool pool for [HTTP::host][HTTP::uri]"} } when LB_SELECTED { if {$switch_debug}{log local0. "[IP::client_addr]:[TCP::client_port]: Selected [LB::server]"} } when SERVER_CONNECTED { if {$switch_debug}{log local0. "[IP::client_addr]:[TCP::client_port]: Connected [IP::server_addr]:[TCP::client_port]"} }

stolivar_88319Thanks Aaron, I put that into play and make the changes to actually reflect our real domain names and pools and I get the following error: Thoughts?01070151:3: Rule [idu-virtual-websites-pool] error:
