Apply an iRule for only a specific pool from a VS

Hi,

I need to apply this iRule to a specific pool, but do not want to impact the other pools in my VS :

when HTTP_REQUEST {

STREAM::disable HTTP::header remove "Accept-Encoding" } when HTTP_RESPONSE {

if {[HTTP::header value Content-Type] contains "text"}{

  STREAM::expression {@http://@https://@}

  STREAM::enable

} }

Can we do it from the webgui ? Or should i add a specific line in my iRule to apply it only on this URL : "alfons-pp.domain.com"

    You are better off using an if-condition for specific domain - alfons-pp.domain.com

    LB::server pool
    gives you the pool of the currently selected member. You can probably use an if-condition to activate the iRule if specific pool is selected, if you are looking for a possible alternate option.

    Hi,

    you can set a variable to define you want the stream to apply:

    when HTTP_REQUEST {
    STREAM::disable 
    if { [HTTP::host] eq "alfons-pp.domain.com" } {
        set stream_string {@http://@https://@}
        HTTP::header remove "Accept-Encoding" 
    } 
}

when HTTP_RESPONSE {
    if { ([HTTP::header value Content-Type] contains "text") and [info exists stream_string]} {
        STREAM::expression $stream_string
        STREAM::enable
    } 
}
