Employeemapclass2node
Along the same lines off an an earlier post by Natty about persistence. I'm trying to just read a cookie that is handed out by the server and persist a user on it. One example is where the cookie is static and therefore, I thought of user mapclass2node.
class nodes {
"s1s1 10.11.1.10:80"
"s1s2 10.11.1.20:80"
}
I'd like to search the request and map as appropriate. I used to do this in the pool with a select command:
select mapclass2node ((http_cookie,("server")),nodes)
How does this work now? Do I need to do a when HTTP_REQUEST and then some if statement.
when HTTP_REQUEST {
if {HTTP::cookie]} {
select mapclass2node((http_cookie,("server")),nodes)
}}

Thanks unRuley and Joe, I will give that a try tonight. Should I set the default pool and the default persistence profile to none?- That's not going to matter as the node command overrides them.
- David_Zuk_10432Well, I gave it a try last night and it doesn't seem to be using the iRule at all. In fact, in my Virtual server, if I didn't have the default persistence set to cookie, if would just follow the round robin rules of the pool. I did write the rule with the log statement, where does that log get written? Also, could this have anything to do with the http profile? Would/should I set up a custom one?
Sorry to be so stubborn and I appreciate the help. - The log outputs to /var/log/ltm.
Unfortunately, it's very hard for us to debug problems like this over the forum as we do not have access to your box. You may want to consider opening a case with support to help you get to the bottom of why your rule isn't being run.
Are you sure the rule is assigned to the virtual server? - David_Zuk_10432Dear Sirs,
I must apologize for my none programming ways. The above examples did in fact work, but I was looking for the wrong thing. Where I was searching for
set server [HTTP::cookie "server"]
I should have been searching for
set server [HTTP::cookie "SERVER"]
I found this out by adding a log statement to tell me what it was finding. I also looked into what the IIS servers were sending out. I appreciate all your help and I have learned a lot from this excersize. And Joe, I would really like to see that list of commands when you get it completed. Thanks again everyone.
Dave
