Irule query to redirect a uri on a new website

Hi All

 

I am looking at an irule to redirect a particular URI to a new site, if certain conditions are meet, i.e a user has a particular cookie set and except if the url contains particular language (defined in the uri i.e lang=fr).

 

I have most of the irule working but need some pointers as I am running into an issue as the redirect to the new site is working but their are absolute paths on the new pages which I am struggling to capture in the same rule.

 

Below is the starting point irule so any pointers or suggestions welcome, I suspect its due to using an if as this is only triggering for /new-path/ and the other uris are then ignored:

 

when HTTP_REQUEST { if { [HTTP::cookie exists "NEWWEBSITE" ] && [HTTP::cookie value "NEWWEBSITE"] equals "1" && [string tolower [HTTP::uri]] starts_with "/new-path/" } { log local0. "cookie exists NEWWEBSITE and /new-path" if {[string tolower [HTTP::uri]] contains "lang=fr" || [string tolower [HTTP::uri]] contains "lang=it" }{ log local0. "contains lang [HTTP::uri], pass to ORIGNAL-WEBSITE" pool ORIGNAL-WEBSITE } else { if {[string tolower [HTTP::uri]] starts_with "/new-path/" || [string tolower [HTTP::uri]] contains "/assets/scripts/" || [string tolower [HTTP::uri]] contains "/assets/styles/" || [string tolower [HTTP::uri]] contains "/assets/fonts/" || [string tolower [HTTP::uri]] contains "/media/" }{ log local0. "contains path [HTTP::uri], pass to NEW-WEBSITE pool" pool NEW-WEBSITE log local0. "Pass to NEW-WEBSITE [HTTP::uri]" } else { pool ORIGNAL-WEBSITE log local0. "pass to ORIGNAL-WEBSITE [HTTP::host][HTTP::uri]" } } } }

 

Thanks in advance

    Hi,

    Your irule had bad structure... you created two filters with the same URI...

    can you try this irule:

    when HTTP_REQUEST {
    set uri [string tolower [HTTP::uri]]
    store lang parameter, blank is not present
    set lang [URI::query $uri lang]
    if { [HTTP::cookie exists "NEWWEBSITE" ] && [HTTP::cookie value "NEWWEBSITE"] equals "1" } {
        switch -glob $uri {
            "/new-path/*" {
                log local0. "cookie exists NEWWEBSITE and /new-path"
                if { $lang equals "fr" || $lang equals "it" }{
                    log local0. "contains lang [HTTP::uri], pass to ORIGNAL-WEBSITE"
                    pool ORIGNAL-WEBSITE
                }
            }
            "*/assets/scripts/*" -
            "*/assets/styles/*" -
            "*/assets/fonts/*" -
            "*/media/*" {
                log local0. "contains path [HTTP::uri], pass to NEW-WEBSITE pool" pool NEW-WEBSITE
                log local0. "Pass to NEW-WEBSITE [HTTP::uri]"
            }
            default {
            pool ORIGNAL-WEBSITE log local0. "pass to ORIGNAL-WEBSITE [HTTP::host][HTTP::uri]"
            }
        }
    }
}

    Thanks for your reply, I realised were I had been going wrong after I posted the question but thanks for pointing out the mistake in my structure, I have re written the irule based on your feedback.
