VIP display page when all servers in pool marked a down, effectively downing the VIP

Question

Hello,
Have users who want a customized web page / splash page that displays custom content such a "This sight is down". &nbsp;
I am still new to the F5's (converting from Cisco CSM's) and was wondering if such customization is possible when a VIP goes down due to all members in pools being marked as down.&nbsp;
Thank you for any assistance,&nbsp;

Et, you can certainly write an irule for this. Check out the codeshare as there should be an example on there.&nbsp;
Alternative is 'fallback host' option in http profile assigned to VIP.&nbsp;
Hope this helps&nbsp;

If I may add, there's a few options:

You can use your own HTML content in an iFile
https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-implementations-11-5-0/27.html?sr=47873155
when HTTP_REQUEST {
    if { [active_members [LB::server pool]] &lt; 1 } {
        set ifileContent [ifile get "/Common/iFile-index.html"]
        HTTP::respond 200 content $ifileContent
        unset ifileContent
    }
}

You can simply respond with some static HTML
when HTTP_REQUEST {
    if { [active_members [LB::server pool]] &lt; 1 } {
        HTTP::respond 200 content "put your html content here"
    }
}

You can issue a redirect to an external page
when HTTP_REQUEST {
    if { [active_members [LB::server pool]] &lt; 1 } {
        HTTP::respond 302 Location "http://notfound.domain.com"
    }
}

Or as Nathan suggests you can simply use the fallback host option in the HTTP profile to force a redirect to an external site.

In all cases though you need a reasonably good monitor applied to the pool.
