Help with maintenance page iRule needed

Hi all, I am working on migration of static maintenance page from stand alone web server to Big-IP. I am sucessfully using iRule below to compile a static page using content uploaded to iFile.

    when HTTP_REQUEST {
    switch [HTTP::uri] {
        "/main.css" {
            HTTP::respond 200 content [ifile get main.css] "Content-Type" "text/css"
        } 
        "/image001.jpg" {
            HTTP::respond 200 content [ifile get image002.jpg] "Content-Type" "image/jpg"
        }
    "/home_bkgrd.gif" {
                HTTP::respond 200 content [ifile get home_bkgrd.gif] "Content-Type" "image/gif"
        }
    "/logo.gif" {
                HTTP::respond 200 content [ifile get logo.gif] "Content-Type" "image/gif"
        }
    "/corporatenav_bkgrd.gif" {
                HTTP::respond 200 content [ifile get corporatenav_bkgrd.gif] "Content-Type" "image/gif"
        }
    "/main_bkgrd.gif" {
                HTTP::respond 200 content [ifile get main_bkgrd.gif] "Content-Type" "image/gif"
        }
    "/logo_print.gif" {
                HTTP::respond 200 content [ifile get logo_print.gif] "Content-Type" "image/gif"
        }
        default {
            HTTP::respond 200 content [ifile get index.htm] "Content-Type" "text/html"
        }
    }
}

I have also uploaded a alternative version of index.htm (index2.htm) that contains slightly different maintenance page message. Challenge is that I need to alternate between index.htm and index2.htm depending on request URI. So per say when request URI eq /companyA index2.htm is served but for any other URI index.htm is served by iRule. Any help is greatly appreciated.

    Hi,

     

    you can change some part of your code as below :

     

    default {
    if { [HTTP::path] eq "/companyA" } {
        HTTP::respond 200 content [ifile get index2.htm] "Content-Type" "text/html"
    } else {
        HTTP::respond 200 content [ifile get index.htm] "Content-Type" "text/html"
    }
}

    If you have several uri to include, you can use a datagroupv:

     

    default {
    if { [class match [HTTP::path] URI_DATAGROUP] } {
        HTTP::respond 200 content [ifile get index2.htm] "Content-Type" "text/html"
    } else {
        HTTP::respond 200 content [ifile get index.htm] "Content-Type" "text/html"
    }
}
