Editing iRule for Maintainance Page with image local in F5 Big-IP iFile

Hi Omran,

Below is the approach that I personally use when creating a maintenance page. It involves creating 3 x iFiles on the BIG-IP; one for your maintenance page HTML, and two others for your logo images. You can then use a switch glob statement to get the BIG-IP to display these files.

Steps

1. Grab all of your maintenance page HTML code and save it into a new file named "maintenance.html"

2. Import maintenance page as an iFile:

  a) Import file in "System iFile List" via GUI: System > File Management > iFile List > Import

  b) Create iFile in "iRule iFile List" via GUI: Local Traffic > iRules > iFile List

3.Create iRule and apply to virtual server

when HTTP_REQUEST {
    if { [active_members [LB::server pool]] == 0 } {
        switch -glob [HTTP::uri] {
            "*Blackboard-LOGO" { HTTP::respond 200 content [ifile get "Blackboard-LOGO"] "Content-Type" "image/png" "Cache-Control"  "no-cache" "Connection" "Close" }
            "*PSAU-LOGO" { HTTP::respond 200 content [ifile get "PSAU-LOGO"] "Content-Type" "image/png" "Cache-Control"  "no-cache" "Connection" "Close" }
            default { HTTP::respond 503 content [ifile get "maintenance.html"] "Content-Type" "text/html" "Cache-Control"  "no-cache" "Connection" "Close" }
        }
    }
}

If you try this, let me know whether or not this works for you.

Cheers,

Michael
