Redirect and Referer in iRules

Hi everyone, I've got what I'm sure is a very simple problem. I am deprecating a URL and for a period of time want to do a 301 redirect and insert a "Referer" value on the redirected traffic so I can see how much was hitting it. I've got this so far as an iRule but it's throwing errors when I try to save it:

 

when HTTP_REQUEST { set refer [HTTP::header "Referer"] {HTTP::header insert “Referer” “foo.bar.com”

 

HTTP::respond 301 Location https://bar.com[HTTP::uri] } }

 

Thanks for any and all help! Sean

    You are trying to insert the header into the inbound request and then send the 301 which obviously won't work. Try this instead.

    when HTTP_REQUEST { 
 HTTP::respond 301 Location "https://bar.com[HTTP::uri]" Referer "foo.bar.com"
}

    Also note your "'s seem slightly wrong, have you pasted from MS Word or something? I've corrected them above.

    In the end I went another way. The "referer" piece didn't work so I added a query that I can track:

     

    when HTTP_REQUEST { if { [HTTP::query] ne "" }{ HTTP::respond 301 Location https://foo.com[HTTP::uri]&fromFoobar=true } else { HTTP::respond 301 Location https://foo.com[HTTP::uri]?fromFoobar=true } }
