Does F5 automatically delete cookies in the header?

I have an issue where cookies are not always showing in the HTTP header. This is causing session timeouts when users are trying to log into a site and when they are randomly clicking around in a site...

Hi can you try adding the following clauses in to help see where it is going missing?;

when HTTP_REQUEST {
set prefix "\[[expr {int (rand() * 10000)}]\] " 
    log local0. "${prefix}Request [HTTP::uri] cookies [HTTP::cookie names]"
}
when HTTP_REQUEST_SEND {
     log local0. "${prefix}Request [HTTP::uri] cookies [HTTP::cookie names]"
}

Then you can keep track of the request as it comes into the F5 and as it is about to leave.

Thanks, IhearF5. I will run the command when we test again. Looking at a previous capture, I see that in the HTTP RESPONSE from the pool member to the F5, the server is returning 3 cookies. However, in the response from the virtual server to the pool member, two of the cookies are not there.
