Simple iRule not working

Hi folks,

 

 

I am having a problem with a simple iRule, I am trying to do the following:

 

 

- mypool1 = www.company.com, has 1 node, virt. server is myvs1

 

- mypool2 = mystring.company.com, has 1 node, virt. server is myvs2

 

 

When a client requests http://www.company.com/mystring I want the clients base url to stay at www.company.com but the data will come from the nodes in the mypool2 servers.

 

 

when HTTP_REQUEST {

 

if { [HTTP::uri] contains "mystring" } {

 

pool mypool2

 

}

 

}

 

 

Initially, when I created this iRule the ltm complained with:

 

 

01070394:3: HTTP_REQUEST event in rule (myRule1)

 

requires an associated HTTP or FASTHTTP profile

 

on the virtual server (myvs1).

 

 

So I went into the myvs1 (and myvs2) virtual servers and changed the http profile to "http", this resolvd the error message however when I point a newly opened IE browser to www.company.com/mystring I get a 404 error. The interesting thing is that if I use the following iRule the uri string matches and I'm redirected to www.google.com:

 

 

when HTTP_REQUEST {

 

set uri [HTTP::uri]

 

if { $uri contains "mystring" } {

 

HTTP::redirect "http://www.google.com/"

 

}

 

}

 

 

Can somebody tell me what I'm missing in this setup?

 

 

Thanks,

    MOst likely you are getting the 404 because mystring is a hook you've added for traffic management purposes, yet isn't a valid destination on your server. If this assumption is correct, you need to remove mystring once your condition is met:

    
when HTTP_REQUEST {
  if { [HTTP::uri] contains "mystring" } {
  HTTP::uri "/"
  pool mypool2
  }
}

    That worked, thanks! I just looked at the web server logs and saw the "GET /mystring/". It's good to know that I should reset the uri for this setup, makes sense.

     

     

    Thanks!
