persistence change from the URI

Hi everyone,

 

 

I'm trying to change the persistence record at will from the URI. Basically, I need to be able to select the pool member that I'm going to in the URI for troubleshooting our custom app. Here's my irule so far. I posted the entire thing so that anyone else that finds it would be able to look at it also:

 

 

when HTTP_REQUEST {

 

 

sets the timer to return client to host URL

 

set sectime 60

 

 

Use the Host header value for the responses if it's set. If not, use the VIP address.

 

if {[string length [HTTP::host]]}{

 

set host [HTTP::host]

 

set errhost1 [HTTP::host]

 

set errhost2 [HTTP::host]

 

} else {

 

set host [IP::local_addr]

 

set errhost1 "site"

 

set errhost2 "the site"

 

}

 

 

Check if the URI is /maintenance

 

switch [HTTP::uri] {

 

"/maintenance" {

 

if { [active_members [LB::server pool] ] > 0 } {HTTP::redirect http://$host}

 

else { HTTP::respond 503 content "Maintenance page content=$sectime;url=http://$host>\

 

 

503 - Service temporarily unavailable

\

 

 

We are performing routine maintenance designed to improve your $errhost1 experience. \

 

We will have $errhost2 up again as soon as possible.

 

\

 

You will be automatically redirected to $errhost2 when it becomes available.

 

" "Content-Type" "text/html"

 

}

 

return

 

}

 

"/F5SERVERINFO" {

 

HTTP::respond 200 content "Pool:[LB::server pool]

 

Backend:[LB::server addr]

 

Port:[LB::server port]

 

Persist:[LB::persist]"

 

}

 

}

 

If the pool is down, redirect to the maintenance page

 

if { [active_members [LB::server pool] ] < 1 } {

 

HTTP::respond 200 content \

 

"

 

 

"

 

return

 

}

 

if { [HTTP::uri] contains "/F5SELECT" } {

 

set backendip [getfield [HTTP::uri] "&" 2]

 

persist uie $backendip [TCP::server_port]

 

HTTP::redirect "http://$host/F5SERVERINFO"

 

}

 

}

 

 

It is getting the IP assigned to the backendip variable correctly, and there's nothing in the logs. But the change in persistence doesn't work. Thanks for any help you can give me!
