Hi Stan,

Thanks for your answer. I am a total beginner on irules so could you please check if this is correct?

when HTTP_REQUEST {
switch -glob [string tolower [HTTP::path]] {
    "/business/portal.*html" {
        pool EXP_business.x.x-static-pool_HTTP
        persist none
        SSL::disable serverside
    }
        switch { [HTTP::host] equals "business.x.x"} {
        {[HTTP::uri] contains "business/portal/"} {
        HTTP::header replace "Host" "x-y-exp.x.x"                         
                    log local0. "Rewrite business portal" 

       "/business/portal.*" {
       pool EXP_business.x.x-https_pool
       log local0. "Default"
    } 

}

}

    Hi,

    your irule format is wrong. you merge if / then / else and switch commands, which worth work.

    switch format is :

    switch [options like --glob, ...] string {
    pattern1 { 
        actions for pattern1
    }
    pattern2 { 
        actions for pattern2
    }
    pattern3 -
    pattern4 { 
        actions for pattern3 and pattern4
    }
    default {
        actions if no previous pattern matches
    }
}

    patterns are string (no condition) which can support wildcard if 

    -glob
    option was set

    if / then / else format is:

    if {condition1} {
    actions for condition1
} elseif {condition2} {
    actions for ondition2
} else {
    actions if no previous condition matches
}

    condition can be 

    [HTTP::uri] equals "/portal/"
