Make your data group look like this, maybe? Then you could write a quick API call to add or subtract hosts from the apology page and not have to worry about listing sites you don't want to take any action on/for.

 

"www.example.com := www.apology.page/example"

 

when HTTP_REQUEST {

 

set host [class match -value [string tolower [HTTP::host]] equals dg_apology_single]

 

if { $host ne "" } {

 

HTTP::redirect "https://$host"

 

unset $host

 

}

 

}

This looks good, but would require alot of tweaking to be able to have 40 different apology URLS.

Every site has a unique apology URL.

Im no expert with using datagroups, but is it possible to have a third colon with the unique aplogoy URL?

So if the DG looks like this:

    site1.com | no  | www.apology.com/23423
    site2.com | no  | www.apology.com/43623
    site3.com | yes | www.apology.com/54233
    site4.com | no  | www.apology.com/68423
    site5.com | yes | www.apology.com/64732

The irule would redirect site3.com to www.apology.com/54233

and redirect site5.com to www.apology.com/64732 ?

I am open for suggestions, or other ways to solve the problem.
