NimbostratusHTTP:cookie doesn't remove with 401 response
I've found that when the server responds with a 401 error my code to remove a cookie does not get sent to the client.
Is that normal functionality for the client to ignore removing a cookie if it is sent a 401 error?

- Could you post your rule so we can see what it is you're doing?

Otto_Schmedlap_Sorry I didn't include the iRule earlier.
I'm just trying to determine the last website I hit(by looking for the HTTP::Header=XYZthewebsite from the web server) to ensure it is the next one I goto until the iRule matches known URIs not on that server. When the URI matches on those other known URIs(like "/" or "/default.aspx") i need to go to another pool until the next time I match on URI="/sites".
However the client continues to respond with the cookie even after I've sent the remove cookie. The only thing I thought was it is related to the 401 response from the server on the request for "/" or "/default.aspx".
