What will happen for the pool redirection if all members are down

 

Hi nitass,

 

Thanks for your inputs and confirmation for resetting the connection when all members are down.

 

I have another iRule - not within the iRule I shared so priority won't differ here.

 

let's say the iRule I shared before is iRule-2, and the other iRule is iRule-1. The name reflect their orders to the VS.

 

iRule-1 has more specific conditions to match i.e the URI will be /xyz/string-1 instead of /xyz*, and when match is there it will redirect, select the same pool (Pool_X) and disable all the events - preventing any further irules processing.

 

From the above, is there any thing causing F5 to forward /xyz* to the default pool.

 

 

iRule-1

 

 

when HTTP_REQUEST {

 

if {([HTTP::header exists "X-Forwarded-For"]) and ([string tolower [HTTP::uri]] contains "/xyz/string-1")} {

 

switch -glob [HTTP::header values "X-Forwarded-For"] {

 

"some-value" {

 

HTTP::redirect "http://www.example.com/xyz/string-2"

 

pool Pool_X

 

event disable all

 

}

 

}

 

}

 

}

 

 

iRule-2

 

 

when HTTP_REQUEST priority 10 {

 

switch -glob [HTTP::path] {

 

 

"/xyz*" -

 

"/YwZ*" -

 

"/AbC*" { pool Pool_X }

 

default { pool Default_Pool }

 

}

 

}
