Rewriting cookies

Hey Guys,

 

I am working on an irule to rewrite cookies on a site with httponly and secure flags set but getting an error on the http only flag sometimes. The rule is below...and this is v11.1

 

 

when HTTP_RESPONSE {

 

set cookie_names [HTTP::cookie names]

 

if { $cookie_names ne "" } {

 

foreach cookie $cookie_names {

 

HTTP::cookie httponly $cookie enable

 

HTTP::cookie secure $cookie enable

 

log local0. "The cookie $cookie was found and attributes modified."

 

}

 

}

 

 

 

 

 

The error I am seeing in the logs is here...

 

 

TCL error: /Common/cookie_rewrite - Improper version (line 4) invoked from within "HTTP::cookie httponly $cookie enable" ("foreach" body line 2) invoked from within "foreach cookie $cookie_names { HTTP::cookie httponly $cookie enable HTTP::cookie secure $cookie enable ..."

 

 

 

 

When I comment out the HTTP::cookie httponly $cookie enable line everything works fine and I succesfully rewrite the secure attr.

 

 

Any ideas?

    I have just encountered exactly the same 'Improper version ' issue with httponly.

     

     

    This is using BIG-IP 11.1.0 HF2, and it appears the issue is with Cookie Version.

     

    For testing reasons, I am attempting to apply the httponly attribute to a persistence cookie (where one can presumably not control the version?).

    persist {
        cookie {
            default yes
        }
    }
    pool foo
    profiles {
