pool pool_allstar_abc

 

} elseif {([HTTP::host] contains "*.xyz.com") } {

 

pool pool_allstar_xyz

 

}

 

}

 

 

 

My problem is that the wildcard does not work if there is a request coming from *.abc.com. Each pool is representing different ports in my configuration. Any experts inputs will be highly appreciated.

    Hi tabkad,

    Try the following 

    
when HTTP_REQUEST {         
               switch -glob [string tolower [HTTP::host]] {               "abc.com" { pool pool_abc}
               "xyz.com" { pool pool_xyz }
               "*.abc" { pool pool_allstar_abc }
               "*.xyz.com" { pool pool_allstar_xyz }
         }
}
    I hope this helps

    Hi Bhattman,

     

     

    I tried the following and it just works. But now I faced another hurdle ,

     

     

    Let me just brief the Application behavior ;

     

     

    First the user will hit the pool_abc and then for authentication it has to go to pool_allstar_abc. After getting authenticated the server does a url redirection which it has to go back again on pool_abc.

     

     

    But for me it does not work with this irule as the traffic comes back as http://*.abc.com:3000 and for this reason the user on the internet does not get any response from the Server.

     

     

    Please advise.
