Disappearing Cookies

First off please excuse my ignorance on this topic, I am very new to this and I am still learning. I'd like to thank everyone in advance for their time and their responses.

 

 

Here is my irule:

 

 

when HTTP_REQUEST {

 

 

Set Variables for manipulation later

 

set URL [HTTP::host]

 

set URI [HTTP::uri]

 

set query [URI::query "$URI"]

 

set referrer [HTTP::header "referrer"]

 

set useragent [HTTP::header "User-Agent"]

 

set cookies [HTTP::cookie names]

 

 

Keep requests from going through if they already have the information needed to authenticate successfully.

 

if {"$URI" contains "SSO" && !("$URI" contains "pfidpadapterid") && !("$URI" contains "favicon.ico")}

 

{

 

if {"$useragent" contains "MSIE"}

 

{

 

HTTP::cookie insert name "pfidpaid" value "IWA" path "/" domain ".yum.com" version 0

 

 

HTTP::cookie insert name "referrer" value "$referrer" path "/" domain ".yum.com" version 0

 

 

foreach cookie [HTTP::cookie names] {

 

log local0. "Cookie $cookie = [HTTP::cookie value $cookie]"

 

log local0. "Cookie $cookie path = [HTTP::cookie path $cookie]"

 

log local0. "Cookie $cookie domain = [HTTP::cookie domain $cookie]"

 

log local0. "Cookie $cookie expires = [HTTP::cookie expires $cookie]"

 

}

 

}

 

else

 

{

 

HTTP::cookie insert name "pfidpaid" value "TAMLDAP2" path "/" domain ".yum.com" version 0

 

HTTP::cookie insert name "referrer" value "$referrer" path "/" domain ".yum.com" version 0

 

HTTP::cookie expires "referrer" 3600 relative

 

foreach cookie [HTTP::cookie names] {

 

log local0. "Cookie $cookie = [HTTP::cookie value $cookie]"

 

log local0. "Cookie $cookie path = [HTTP::cookie path $cookie]"

 

log local0. "Cookie $cookie domain = [HTTP::cookie domain $cookie]"

 

log local0. "Cookie $cookie expires = [HTTP::cookie expires $cookie]"

 

}

 

}

 

}

 

else

 

{

 

return

 

}

 

}

 

 

As you can see I am setting a couple of cookies in the HTTP_REQUEST. I can see these cookies in the LTM log via the logging that I have setup, but I am unable to see these cookies in the browser using a tool like the FireFox plugin "Web Developer".

 

 

I tried using the HTTP::cookie expires functionality, but it appears that you can only do that in the HTTP_RESPONSE and when I check for that cookie in HTTP_RESPONSE I cannot find it.

 

 

At first I thought this was the backend server deleting the cookies, but I setup a virtual server that was pointing to a basic Apache web server and used a static HTML page to test this irule and I was still unable to see the cookies that were set.

 

 

Any help that you can provide on this would be most appreciated. Thank you again in advance.

    I think you have the answer above from yourself... HTTP::cookie in a REQUEST adds the cookie to the REQUEST. (BigIP to pool member). NOT to the response. if you want a cookie to be set on the browser, you need to add it in the HTTP_RESPONSE event.

  • Hamish, thank you for your response. I need the cookies to go to the pool member for use later, but I would still expect to see those in the browser. For example, I can see session and/or persistence cookies in the browser. Is there a way to make the cookies that I set in the HTTP_REQUEST a session cookie so that it will stick around for use throughout the session?

    Hi.

     

     

    That woulld normally require the server to recognise that cookies were being presented that it hadnt set, and set them again... Which wouldnt be very good.

     

     

    A better way is for the irule to remember which cookies were added in the request and then set them in the response as well, so theyre persisted in the browser.
