HTTP redirect to Pools members

Try this:

when HTTP_REQUEST {
   switch -glob [string tolower [HTTP::uri]] {
      "/url1" {
         pool pool1  
      }
      "/url2" {
         pool pool2
      }
      default {
         pool pool1  
      }
   }
}

Again, forgive the stupidity here.

 

 

I have a pool of 2 servers calle "web".

 

 

What would be the syntax that I would place in the iRule that would load balance to web traffic?

 

 

Thanks

This is assuming that you have more than one pool of web servers, otherwise configure the virtual server profile to point to a single defined pool on the resources tab.

when HTTP_REQUEST {
   switch -glob [string tolower [HTTP::uri]] {
      "/url1" {
         pool web
      }
      "/url2" {
         pool web2
      }
      default {
         pool web
      }
   }
}

"default" should point to whichever pool you want traffic to go to if the uri is different than those defined in the statement.

Along those same lines, I need to retain the full URI coming in. So, url1/otherfile.html also needs to be directed to pool web, but keep it's full path. Would this rule above still be valid?

 

Also, how do I handle someone coming in as http://www.mysite.com/ with no URI, I need a URI of "/" to redirected to correct pool as well.

The uri won't be affected by the load balancing, so the server will get the whole thing. There's two ways to catch the base "/", using this structure, that I can think of. Perhaps one of the gurus can confirm this:

1. the "default" case will catch everything not specifically defined, including the "/".

2.

when HTTP_REQUEST {
   switch -glob [string tolower [HTTP::uri]] {
      "/url1*" {
         pool web
      }
      "/url2*" {
         pool web2
      }
      "/" {
         pool web
      }
      default {
         pool web
      }
   }
}

I threw the "*" in after the uri in case there's additional text after it.

if you have a lots of different uri to filter you should have a look at creating class with the findclass commands: Click here

 

 

Usually using a class is more eficient when you have more than 100 different data to filter
