404 redirect with URL Persistance?

Hello,

We have 2 nodes in a pool with health monitors on Port 9120.

I was able to create a http profile that does a 404 redirect to a third node if the health monitor shows all server pool members down. Then it was asked that we keep URL persistence so if the redirect happens http://mysite.com stays http://mysite.com rather than .

I was able to test this iRule:

when CLIENT_ACCEPTED { if { [active_members [LB::server pool]] == 0 } { pool mythirdnodepool } }

Only issue is they want mythirdnode/a/404.html

Can anyone help me modify this iRule to make the redirect happen but instead of just the default /get have it be mysite.com/a/404.html?

Thank you

    A word of caution: when faced with uncommon requests by customer, try to ask why they want it this specific way. Quite a few times, such requests are put forth based on faulty assumptions which can be solved in alternate simpler options or simple explanation.

    when HTTP_REQUEST {
if { [active_members [LB::server pool]] == 0 } {
HTTP::uri "/a/404.html" 
pool mythirdnodepool
}
}
