iRule that redirects client to FTP from HTTP if downloading file greater than 10 MB

I got it to work. It looks like this right now:

 

 

when HTTP_REQUEST {

 

if { [HTTP::uri] ends_with ".exe"}{

 

set uri [HTTP::uri]

 

log "here1"

 

}

 

}

 

when HTTP_RESPONSE {

 

if {[HTTP::header "Content-Length"] >= 1048576 && [HTTP::header "Content-type"] contains "application" }{

 

HTTP::redirect "ftp://user1:useruser@192.168.0.1:21$uri"

 

log "here2"

 

}

 

}

 

 

The only problem is that before the download from FTP start it takes about 1 minute for BIG-IP to process (I'm using virtual edition). Logs are generated immidiately and I'm confused why redirect isn't sent immidiately too. After analysing tcpdump on server side it seems that BIG-IP is downloading whole file first before user is redirected to FTP server. How to fix it or how should I do this properly?

 

 

Please help me guys.

You could try the following...

HTTP::response 302 Location "ftp://user1:useruser@192.168.0.1:21$uri" Connection Close

Not sure if it will help but its worth a try.

Can't edit my post above... stupid website. Had a typo.

 

 

HTTP::respond 302 Location "ftp://user1:useruser@192.168.0.1:21$uri" Connection Close

Follow that with:

 

 

TCP::close

 

return

 

 

 

when HTTP_RESPONSE {

 

if {[HTTP::header "Content-Length"] >= 1048576 && [HTTP::header "Content-type"] contains "application" }{

 

HTTP::respond 302 Location "ftp://user1:useruser@192.168.0.1:21$uri" Connection Close

 

log "here2"

 

TCP::close

 

return

 

}

 

}
