URL Redirect

I need to create an irule to redirect certain URI strings to a specific pool on my F5 device. Sound simple enough but I am having issues writing the irule to match the specific URI's.

 

 

The uri's are as follows...

 

https://xyz.net.au

 

https://xyz.net.au:8181/webex or

 

https://xyz.net.au:8443/webex

 

 

 

The iRule I created and is failing is as follows...

 

 

 

when HTTP_REQUEST {

 

switch -glob [HTTP::host] {

 

"xyz.net.au {

 

switch -glob [HTTP::uri] {

 

":8181/*" { use pool Port_XYZ_8181 }

 

":8443/*" { use pool Port_XYZ_8443 }

 

default { use pool Pool_XYZ }

 

}}}}

 

 

 

When broswing to https://xyz.net.au, the web data is redirect and the web page is displayed. When trying xyz.nbet.au:8181/webex the redirect fails. I suspect the irule does not match the :8181/*

 

How can I write this irule to meet my needs?

 

Please help.

    i understand port number e.g. 8181, 8443 is not in HTTP::uri. it is in HTTP::host.

     

     

    by the way, is virtual server listening on any port?

    => This is correct, was a typo on my part

    Yes, the VS is listening on the ports 8181 and 8443.

     

     

    I have been asked to redirect a different HTTP::Host which comes in on the same IP address but needs to redirect to a different pool, hence the need to redirect the HTTP::host to a specific pool accordingly.

    Solution privided has been implemented and tested successfully...

     

     

    iRule is as follows now

     

     

     

    if {[HTTP::host] contains "xyz.com.au"} {

     

    switch [getfield [HTTP::host] ":" 2] {

     

    "8181" {

     

    pool Prod_XYZ_8181

     

    }

     

    "8443" {

     

    pool Prod_XYZ_8443

     

    }

     

    }

     

    }

     

    }
