NimbostratusiRule that redirects client to FTP from HTTP if downloading file greater than 10 MB
Hello.
I would like to write an iRule that redirects client from HTTP to FTP while downloading file larger than 10MB. Could you help me please? This doesn't work at all:
when HTTP_RESPONSE {
if {[HTTP::header exist "Content-Length"] && [HTTP::header "Content-Length"] >= 10485760 && [HTTP::header "Content-type"] contains "application" }{
HTTP::redirect "ftp://user1:useruser@192.168.0.10[HTTP::header "Content-Location"]"
}
}
Thank you in advance
Peter

killyou_51014I 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$uri" Connection Close
Not sure if it will help but its worth a try.
Kevin- Kevin_Davies_40Can't edit my post above... stupid website. Had a typo.
HTTP::respond 302 Location "ftp://user1:useruser@192.168.0.1:21$uri" Connection Close
Kevin - 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
}
}
