Cookies

Hi

 

Im having an issue with Cookies not being accepted at the server unless they are within the same Cookie header:

 

Cookie: blah=blah; blahs=blahs;

 

If there are two Cookie headers then it ignores the second one (the second one is added in the irule):

 

Cookie: blah=blah other HTTP headers.... Cookie: blahs=blahs.

 

Is it possible to merge all cookies into one Cookie header using an irule and also add a cookie generated within the irule in the merge?

 

Thanks Bryan

    I have:

     

    when HTTP_REQUEST {

     

    Merge cookies and insert cookie that changes the URL

    set hostaddr [HTTP::host]

     

    set existing cookies

    set cookie_names [HTTP::cookie names] if { $cookie_names ne "" } { foreach cookie $cookie_names { set cookie_value [HTTP::cookie $cookie] HTTP::cookie remove $cookie HTTP::cookie insert name $cookie value $cookie_value path / version 1 } } }

     

    But I want to also merge a new cookie generated in the irule such as this:

     

    HTTP::header insert "Cookie" "Url=https://$hostaddr/server.aspx"

    You could grab the header value when it comes in and then append your additional cookie and remove the header then readd it. Something like this...

    set cookie [HTTP::header value "Cookie"]
HTTP::header remove "Cookie"
append cookie "; name=value"
HTTP::insert name Cookie value $cookie

    you could use HTTP::header values instead of value.

    e.g.

     configuration

[root@ve11a:Active:In Sync] config  tmsh list ltm virtual bar
ltm virtual bar {
    destination 172.28.24.10:80
    ip-protocol tcp
    mask 255.255.255.255
    pool foo
    profiles {
        http { }
        tcp { }
    }
    rules {
        qux
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    vs-index 12
}
[root@ve11a:Active:In Sync] config  tmsh list ltm pool foo
ltm pool foo {
    members {
        200.200.200.101:80 {
            address 200.200.200.101
        }
    }
}
[root@ve11a:Active:In Sync] config  tmsh list ltm rule qux
ltm rule qux {
    when HTTP_REQUEST {
  set cktmp ""
  foreach ck [HTTP::header values Cookie] {
    if { $cktmp eq "" } {
      append cktmp $ck
    } else {
      append cktmp "; $ck"
    }
  }
  HTTP::header remove Cookie
  HTTP::header insert Cookie $cktmp
}
}

 test

[root@ve11a:Active:In Sync] config  ssldump -Aed -nni 0.0 port 80
