Can anyone help me with single apology page using data groups?

Question

Hi,
I have a VS that serves several sites. Some times, one of these sites malfunction and I want to be able to manually put it in apology in a easy way. 
Im thinking a datagroup with a string and a value will be easy enough, like this:
site1.com | no
site2.com | no
site3.com | yes
site4.com | no
site5.com | no

Site 3 will be put in apology (just a 301 redirect to a static URL. Every site has a different URL.)
My logic is:
If HTTP::host equals class match dg_apology_single and class match apology_dg_single value equals "yes" 
then: 301 to http://apology.com/site3
else: do nothing.
Im having some problems creating the logic. Any help would be appreciated!

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.&nbsp;
"www.example.com := www.apology.page/example"&nbsp;
when HTTP_REQUEST {&nbsp;
set host [class match -value [string tolower [HTTP::host]] equals dg_apology_single]&nbsp;
if { $host ne "" } {&nbsp;
HTTP::redirect "https://$host"&nbsp;
unset $host&nbsp;
}&nbsp;
}&nbsp;

Hmm, Im not sure if I follow.&nbsp;
Writing a API to manage the hosts sounds like a bit to much work. Not knowing exactly how to do so.&nbsp;
Having all my sites in the datagroup, predefined with a simple Yes/no value will be easy for others to manage. &nbsp;
If site3 is experiencing problems, one just has to change a no to yes. &nbsp;
I think the hard part is to have a single site redirect to a unique URL, if a "yes" is present.&nbsp;

I don't like the way this plays out in a large environment, but if this is how you want to do it... Also if you want to append something relevant to site3 aspart of the URI in the redirect, it'll take a bit more work.&nbsp;
www.site3.com := yes&nbsp;
when HTTP_REQUEST {&nbsp;
set host [class match -value [string tolower [HTTP::host]] equals dg_apology_single]&nbsp;
if { $host eq "yes" } {&nbsp;
HTTP::redirect "https://apology.page"&nbsp;
unset $host&nbsp;
}&nbsp;
}&nbsp;
