404 redirect based on URI

I have an almost identical code block

 

when HTTP_REQUEST { 
   set uri [string tolower [HTTP::uri]] 
   set host [HTTP::host] 
 } 
 when HTTP_RESPONSE { 
   if {([HTTP::status] equals 404) and ($uri equals "/fnf.asp")} { 
     log local0. "404 : http://$host$uri" 
     HTTP::respond 302 Location "http://$host" 
   } 
 }

 

My 404 is logged to /var/log/ltm

 

But I don't see a response.

 

Using http://web-sniffer.net, I don't even see a response code.

 

Using telnet from the BIGIP shell, I get a disconnect message.

 
   telnet {bigip.ip} 80 
   GET /fnf.asp HTTP/1.0 
   HOST: {fqdn} 
  
   Connection closed by foreign host. 
 

 

 

I've tried a few different configurations,

 

HTTP::redirect,

 

HTTP::respond 200 Content "content",

 

HTTP::header replace Status 302

 

 

If I comment out the Respond/Redirect, the client sees the 404 message.

 

But with that line in there, the client sees nothing.
