Return the custom error page to client

You have several different options, I haven't included all of them... You can find more in the CodeShare:

Rather than sending the status codes you can set the response type to whatever status code you wish and redirect the traffic to a specified location:

 

when HTTP_RESPONSE {
     if { [HTTP::status] == "403" } {
         HTTP::respond 200 Loccation "http://www.customerrorpage.com"
     }
     elseif { [HTTP::status] == "404" } {
         HTTP::respond 200 Loccation "http://www.customerrorpage.com"
     }
}

 

 

Rather than sending the status codes you can use a 301 redirect:

 

when HTTP_RESPONSE {
     if { [HTTP::status] == "403" } {
         HTTP::redirect "http://www.customerrorpage.com"
     }
     elseif { [HTTP::status] == "404" } {
         HTTP::redirect "http://www.customerrorpage.com"
     }
}

 

 

Rather than sending the status codes you send a custom response:

 

when HTTP_RESPONSE {
     if { [HTTP::status] == "403" }
     HTTP::respond 200 content "Forbidden
    
    
    
    Website Error:  Forbidden
    NOTICE: Website has experienced an error.
    "
 }
     elseif { [HTTP::status] == "404" } {
                          HTTP::respond 200 content "File Not Found
    
    
    
    Website Error:  File Not Found
    NOTICE: Website has experienced an error.
    "
     }
}

The first two seem to have blown up during the first post:

when HTTP_RESPONSE {
     if { [HTTP::status] == "403" } {
         HTTP::respond 200 Loccation "http://www.customerrorpage.com"
     }
     elseif { [HTTP::status] == "404" } {
         HTTP::respond 200 Loccation "http://www.customerrorpage.com"
     }
}

Rather than sending the status codes you can use a 301 redirect:

when HTTP_RESPONSE {
     if { [HTTP::status] == "403" } {
         HTTP::redirect "http://www.customerrorpage.com"
     }
     elseif { [HTTP::status] == "404" } {
         HTTP::redirect "http://www.customerrorpage.com"
     }
}

Thanks for all helps。 But，those error code was returned form web server， all server is down，Who returns the error code at this time?

Are you tring to return an error page when all servers in your pool are down?
