uncommon loadbalancing requirement

Hi Thorsten,

You're right, you have to use priority groups.

Regarding your needs on checking URI, here is an iRule :

when HTTP_REQUEST { 
    if { [HTTP::uri] starts_with "/company/test1" and [LB::server addr] equals "Your_member_IP"}{   
        return;
    }
    else {
        discard;
    }
}

Hi Thorsten,

    else {
        discard;
    }
}

Hi again,

I had to change the iRule a little bit to fit my needs, but unfortunately it doesn't work. Thats my iRule:

when HTTP_REQUEST { 
if { (not [HTTP::uri] contains "/test1") and [LB::server addr] equals "10.10.10.3"}{   
    discard;
    }
}

But my Browser only shows the index.html if the iRule is not activated. Did I mess sth. up?

Hi Thorsten,

I made a mistake and I didn't see it before... I'm sorry 😕

Here is the good event matching your needs :

when LB_SELECTED { 
if { (not [HTTP::uri] contains "/test1") and [LB::server addr] equals "10.10.10.3"}{   
    discard;
    }
}

Hi Thomas,

no problem :). I'm happy that you took time to think about my problem and even if the iRule was not working, you pushed me in the right direction. I am just playing around with the iRule and figured out, that is does not work because [LB:server addr] has no value.

Regarding your latest suggestion, I am not sure if the event LB_SELECTED will work for the [HTTP:uri] command. I'm afraid it will work for [LB:server add] but not for [HTTP:uri] because the reference of [HTTP:uri] says:

Valid Events:
CACHE_REQUEST, CACHE_RESPONSE, HTTP_CLASS_FAILED, HTTP_CLASS_SELECTED,  HTTP_REQUEST, HTTP_REQUEST_DATA, HTTP_REQUEST_SEND, REWRITE_REQUEST_DONE, SERVER_CONNECTED

What can I do? Do I have to check two events? Is that possible?

Thanks, Thorsten

So, I am not totally through with testing, but Thomas' solution seems to work. Can anyone explain the sense of "Valid events" to me?

Regard,

Thorsten

Thanks a lot Thomas. I went through the web based training for iRules, but thats just good to get a rough overview. But today I learned many things about troubleshooting iRules :-)
