Operation not supported. Multiple redirect/respond invocations not allowed

I am receiving the following error in the ltm log (private data has been modified).

 

TCL error: redirect_irule - Operation not supported. Multiple redirect/respond invocations not allowed (line 9) invoked from within "HTTP::respond 307 "Location" "https://www.fruit.com[HTTP::uri]"

 

I have seen previous posts on the error, but cannot find a way to perform all of the redirects without multiple response/redirect lines in the irule. The iRule is listed below.

 

when HTTP_REQUEST { set host [HTTP::host] set uri [HTTP::uri]

 

switch -glob [string tolower [HTTP::host]] { "lemons.com" { HTTP::respond 301 "Location" "https://www.fruit.com/links/test?[HTTP::query]" } } if { $host contains "apples.com" and $uri contains "tree" } { HTTP::respond 307 "Location" "http://web.fruit.com/tree.aspx" } else { HTTP::respond 307 "Location" "https://www.fruit.com[HTTP::uri]" } }

 

The goal is to have the redirects in place. Currently, the LTM is intermittently sending resets (RSTs) back to the client for www.lemons.com and lemons.com. Sometimes the browser issues a redirect and other times it doesn't due to the reset.

 

www.lemons.com -> redirect to https://www.fruit.com/links/test?[HTTP::query] lemons.com -> redirect to https://www.fruit.com/links/test?[HTTP::query] www.apples.com -> redirect to https://www.fruit.com apples.com/tree -> redirect to https://www.fruit.com/[HTTP::uri]

 

Thanks.

    The easiest way to handle this is to do a TCP::Close followed by return

     

    As long as that is the only iRule doing redirects, you should stop seeing the warnings in the log.

    Is this logic the same as what you need? would it work better?

    when HTTP_REQUEST { 
    set host [string tolower [HTTP::host]]
    set uri [HTTP::uri]

    if {$host equals "lemons.com" } {
        HTTP::respond 301 "Location" "https://www.fruit.com/links/test?[HTTP::query]"
    } elseif { $host contains "apples.com" and $uri contains "tree" } { 
        HTTP::respond 307 "Location" "http://web.fruit.com/tree.aspx" 
    } else { 
        HTTP::respond 307 "Location" "https://www.fruit.com[HTTP::uri]" 
    } 
}
