Persist cookie serverID iRule

This is the full Brocade rule. I was able to build the iRule for the other CSW rules below. But I couldn't find an equivalent iRule for the one I mentioned in the actual question.

 

csw-rule "path" url equals "/"

 

csw-rule "sticky" header "cookie" search "ServerID="

 

csw-policy "vip"

 

match "path" redirect "*" "/xyz" ssl

 

match "sticky" persist offset 0 length 4 group-or-serverid

 

default forward 1

 

default rewrite insert-cookie "ServerID" " * " " * " 60

 

I thought the iRule would look something like the below. I am not sure if the below one is right. But still working on putting together all the pieces.

 

when HTTP_REQUEST {

 

if { [HTTP::uri] equals "/" }{

 

HTTP::redirect "https://[HTTP::host]/arch" }

 

elseif { [HTTP::header "cookie"] equals "ServerID=" } {

 

persist cookie

 

}

 

else {

 

pool default_pool

 

HTTP::cookie insert ServerID

 

} }
