Force node selection on the URL

Thanks for your reply.

 

 

I want to choose a node within a pool and not between pools. It will be one pool which has multiple members and they all got to be tested seperately.

 

 

Rama.

Here is one option:

1. Create 2 pools, one for each webserver. Call these pools webserver1 and webserver2.

2. Create a Rule to switch on the http_uri. Call this "node_switcher"

if (http_uri ends_with "webserver1") { 
    use pool webserver1 
 } 
 else { 
    if (http_uri ends_with "webserver2") { 
       use pool webserver2 
    } 
    else { 
       discard 
    } 
 }

3. Create the VIP based on the Rule "node_switcher".

Now When the a request comes in to the specified VIP, it will be processed by the rule and forwarded to either the webserver1 or webserver2 pool (or be discarded - you might want to change this behavior).

Hope this helps.

Since this is more of a BIG-IP configuration question (not iControl related), I'd recommend you contact F5 Customer Support (or take a look at the Solution Center) directly.

Here's the feedback from one of our UIE experts:

 

 

This can be done with direct node selection (the use of the select statement on the pool). Basically, you create a mapping of text->node in a class and then specify an expression to select the text. It's ugly, but it works and it would look something like this:

 

 

class myClass {

 

"webserver1 10.10.10.1"

 

"webserver2 10.10.10.2"

 

}

 

 

pool myPool {

 

member 10.10.10.1

 

member 10.10.10.2

 

select mapclass2node(findstr(http_uri,"?",1), myClass)

 

}

 

 

Note that no rule is used.
