Schedule iRule

Hi Steve,

You can look on the CLIENT_ACCEPTED event Wiki page to see a list of available commands in that event.

You are correct that you cannot use an HTTP::redirect or HTTP::respond in that event. You could however set a flag / variable in this event that is picked up in the HTTP_REQUEST event and triggers a redirect.

Here's an example:

 
when CLIENT_ACCEPTED {
 Check Client IP Address Exclusions GO HERE!
if { !([matchclass [IP::remote_addr] equals $::MaintenancePageOverride ]) } {

 If it's not on the exclusion list.  Tag it here.
set rewrite_response 1
} else {
 If it is to be excluded, set value here.
set rewrite_response 0
}
}
when HTTP_REQUEST {
if { [HTTP::uri] contains "maintenanceaccess" } {
set rewrite_response 3
}
}
when HTTP_RESPONSE {
if { $rewrite_response equals "1" } {
HTTP::respond 200 content "Site unavailable



System Maintenance
NOTICE: This website down for system maintenance. 

"
}
elseif { $rewrite_response equals "3" } {
HTTP::respond 200 content "Maintenance Access



Maintenance Access Assistance
Your IP Address is: [IP::client_addr] 

Please provide the IP Address listed above to the Support Team Representative assisting you with
your maintenance window.  This will allow the Representative to grant you override access to the
maintenance page.

Thank you.
