    Hi,

    in your irule, you get request parameters with good command, but when you change it, you only modified HTTP::path...

    HTTP::host "[HTTP::host]:3333"
HTTP::path "/ap-webconsole"

    another point is to replace /db/ap-webconsole with /ap-webconsole

    HTTP::path [string map {/db/ap-webconsole /ap-webconsole} [HTTP::path]]

    so can i try as below

     

    Code
when HTTP_REQUEST {
log local0. "Original path: [HTTP::path]"
log local0. "Original uri: [HTTP::uri]"
if { [HTTP::uri] starts_with "/db/ap-webconsole" }{ 
HTTP::host "[HTTP::host]:3333"
HTTP::path [string map {/db/ap-webconsole /ap-webconsole} [HTTP::path]]
log local0. "Pool app1 chosen" 
pool app1 
log local0. "Modified uri: [HTTP::uri]"     }
else {
log local0. "Pool app2 chosen" 
 pool app2
}
}

    still i am getting error on line 5 , how we can modify the host with :3333 or use respond location 301 because backend http host is change to something else do i required to modify the response as well with stream profile ? pls assist

    Hi,

    try this irule:

    when HTTP_REQUEST {
    switch -glob -- [HTTP::path] {
        "/db/ap-webconsole*" {
            HTTP::respond 301 noserver Location [string map {/db/ap-webconsole /ap-webconsole} [HTTP::uri]]
        }
        "/ap-webconsole*" {
            HTTP::header replace Host "[HTTP::host]:3333"
        }
        default {
            HTTP::respond 302 noserver Location "/ap-webconsole/"
        }
    }
}
