Old story - maintenance page iRule

Hello,

I know this topic has been discussed many times already but there is one thing I got stuck with - is it possible to combine two of these actions into a single iRule? :

when HTTP_REQUEST {
      HTTP::respond 200 content {
      
      The site has been moved
      
      The webiste has moved to https://aaa.aaa
      Please update your bookmarks.
      
      
   } 
}

and this:

HTTP::respond 200 content [ifile get we_have_moved] "Content-Type" "image/gif" }

The idea is to have a tiny HTML page with ifile inserted image.

Thanks and appologies for my possible WEB-ignorance.

    I think this thread may help you.

     

    irule-maintanance-page-with-ifile

     

    Basically, you set up an iRule with a default action that posts your HTML, with the contexts above for the subsequent content calls for the iFiles.

     

    Hope it helps!

    Thanks David! It really helped me to get into this. Just one more thing here - I'm trying to use a variable below (REDIRECTURL) to simplify future modifications, but when I try to use it within HTTP:respond code it doesn't return variable value and just prints it as a text "$REDIRECTURL".

     

    when HTTP_REQUEST {
set REDIRECTURL "https://example.com"
switch [HTTP::uri] {
    "/we_have_moved.png" {
        HTTP::respond 200 content [ifile get we_have_moved.png] "Content-Type" "image/gif"
    }
    default {
        HTTP::respond 200 content {
            
            The site has been moved
            
            The webiste has moved to 
            Please update your bookmarks!
            You will be redirected in
            50 seconds 
            ![HTML5 Icon](we_have_moved.png)
            
            
            
            }
        }
    }
}

    Is there any way to make this work?

     

    Thanks!

    Try this then:

    when HTTP_REQUEST {
    set REDIRECTURL "https://example.com"
    set message "
            The site has been moved
            
            The webiste has moved to 
            Please update your bookmarks!
            You will be redirected in
            50 seconds 
            !\[HTML5 Icon\](we_have_moved.png)
            
            
            "

    switch [HTTP::uri] {
        "/we_have_moved.png" {
            HTTP::respond 200 content [ifile get we_have_moved.png] "Content-Type" "image/gif"
        }
        default {
            HTTP::respond 200 content $message
        }
    }
}

    Or:

    when HTTP_REQUEST {
    set REDIRECTURL "https://example.com"
    switch [HTTP::uri] {
        "/we_have_moved.png" {
            HTTP::respond 200 content [ifile get we_have_moved.png] "Content-Type" "image/gif"
        }
        default {
            HTTP::respond 200 content "\
            The site has been moved\
            
            The webiste has moved to \
            Please update your bookmarks!\
            You will be redirected in\
            50 seconds \
            ![HTML5 Icon](we_have_moved.png)\
            \
            \
            "
        }
    }
}
