Basic 404 prevention iRule not working in IE (Firefox fine)
I have a basic 404 prevention iRule that sends one message if we receive a 404 from the backend, and another message if the pool members are not available. The rule works 100% in Firefox, but does no...
Got it all working, and have answers for all of the behavior. So with the iRule, 404 prevention worked fine in all browsers except IE 6 at the customer site. Turns out they had some custom IE build that was somehow causing resets instead of 404s (no clue how). I had them reset IE 6 settings to default, and 404's started working. However, server down prevention messages didn't work in any browser, anywhere due to the LB::Failed usage in my iRule. I tested this using both a purposefully broken monitor, as well as simply disabling the server. I ended up switching LB::Failed to:
when HTTP_REQUEST {
if { [active_members http_pool] < 1 } {
HTTP::respond 200 content [subst $::Servers_down]
}
}
Thanks for all the responses
