Regex to irule

Hi All,

 

I'm new to Irule and find difficult to migrate this regex into irule

 

Regex RewriteRule ^/company/(.*)(?http://www.test.com/company/$1/en_gb [R=301,L]

 

My config

 

"/company/*" { HTTP::redirect "http://www.test.com[HTTP::uri]en_gb"

 

Condition: if Uri matched "/company/*"(wildcard) then the suffix "/en_gb" should added for all company starting uri

 

Ex: /company/auto ---> company/auto/en_gb

 

/company/bike ---> company/bike/en_gb

 

many webpages have same condition looking,

 

appreciate irule coders.

    Hi,

    the irule below is a basics for your need : 

    when HTTP_REQUEST {
    if { [HTTP::path] starts_with "/company" and !([HTTP::path] contains "en_gb") } {
        set uri "http://www.test.com[HTTP::path]/en_gb"
        HTTP::respond 301 noserver "Location" "$uri" Cache-Control" "no-cache, must-revalidate"
    }
}

    Hope this help

    Here the same irule a bit modified to fit for all webpages you need to rewrite :

    For this one, you will need to create a string datagroup first named "rewrite_uri" and add all your starts uri (/auto, /bike, etc.)

    when HTTP_REQUEST {
    if { [class match [HTTP::path] starts_with rewrite_uri] and !([HTTP::path] contains "en_gb") } {
        set uri "http://www.test.com[HTTP::path]/en_gb"
        HTTP::respond 301 noserver "Location" "$uri" Cache-Control" "no-cache, must-revalidate"
    }
}

    And this one take into account Query string that may be present in the initial request : 

    when HTTP_REQUEST {
    if { [class match [HTTP::path] starts_with rewrite_uri] and !([HTTP::path] contains "en_gb") } {
        if { [HTTP::query] eq "" } {
            set uri "http://www.test.com[HTTP::path]/en_gb"
        } else {
            set uri "http://www.test.com[HTTP::path]/en_gb?[HTTP::query]"
        }
        HTTP::respond 301 noserver "Location" "$uri" Cache-Control" "no-cache, must-revalidate"
    }
}
