virtual bar {
   snat automap
   pool foo
   destination 172.28.65.152:http
   ip protocol tcp

   profiles {
      http {}
      stream {}
      tcp {}
   }
}
[root@ve1023:Active] config  b pool foo list
pool foo {
   members 200.200.200.101:http {}
}
[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
        STREAM::disable

        if {[HTTP::version] eq "1.1"} {
                if { [HTTP::header is_keepalive] } {
                        HTTP::header replace "Connection" "Keep-Alive"
                }
        }
}

                STREAM::expression "@@@"
                STREAM::enable
        }
}

when STREAM_MATCHED {
        STREAM::disable

Thanks nitass

sorry it appears HTTP::version 1.0 command is missing.

this is the revised one.

[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
        STREAM::disable

        if {[HTTP::version] eq "1.1"} {
                if { [HTTP::header is_keepalive] } {
                        HTTP::header replace "Connection" "Keep-Alive"
                }
                HTTP::version 1.0
        }
}

when HTTP_RESPONSE {
        if {[HTTP::header Content-Type] starts_with "text/"} {
                STREAM::expression "@@@"
                STREAM::enable
        }
}

when STREAM_MATCHED {
        STREAM::disable
}
}

Hi Nitass,

 

 

Hum,

thanks! i tested and it seemed to be okay, so i thought it might be fine. i moved the script to be inside head tag as follows.

[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
        STREAM::disable

        if {[HTTP::version] eq "1.1"} {
                if { [HTTP::header is_keepalive] } {
                        HTTP::header replace "Connection" "Keep-Alive"
                }
                HTTP::version 1.0
        }
}

when HTTP_RESPONSE {
        if {[HTTP::header Content-Type] starts_with "text/"} {
                STREAM::expression "@@@"
                STREAM::enable
        }
}

when STREAM_MATCHED {
        STREAM::disable
}
}

[root@ve1023:Active] config  curl -i http://172.28.65.152
