Redirect a VS via irule

We are running a Bigip v11.4.1 build 647.0

 

I would like to redirect a VS that we have on our F5 to a different url. For example, the user points their browser to www.school.com. The VS that corresponds to www.school.com has an irule assigned to it. I would like the irule to put up a quick informational web page that says that they are being redirected to www.highschool.com because www.school.com has been retired. The informational page should wait a few seconds so they can read it (maybe 5 seconds), then redirect them to www.highschool.com. I tried the following irule, but it just redirects without showing them the informational web page:

 

when HTTP_REQUEST { set delay 5 HTTP::respond 200 content "https://www.highschool.com/> The Test site www.school.com has been retired. After 5 seconds, youll automatically be redirected to our new home page at www.highschool.com. " "Content-Type" "text/html" }

 

What am i doing wrong? Or is there a better way to do this on the F5?

    Hi Danny,

     

    do you see error messages in /var/log/ltm when the iRule is triggered?

     

    ("tail -f /var/log/ltm")

     

    I believe it is necessary to escape all quotas in the specified content as you did with the \"REFRESH\" in the meta tag. I would also recommend to avoid the usage of the delay variable and hard code the refresh rate instead to simplify things.

     

    Personally I prefer to put content into a $payload variable (using "append" to combine with other variable parameters) and to reference it in the HTTP::respond 200 content "$payload".

     

    Thanks, Stephan

    The following seemed to work for me: 

    when HTTP_REQUEST {
    set page "
    The Test site 
    has been retired. After 5 seconds, youll automatically be redirected to our new home page at
    "
    HTTP::respond 200 content "${page}" Content-Type "text/html"
}
