Redirect iRule with URI redirection and pool distribution

Hi,

 

I have an iRule that redirects URI containing certain syntax. I want to add a switch -glob statement so that the group of URI's that 'starts_with' the /page1, /page2, on so forth gets sent to a certain pool else defaults to pool green. I put in:

 

Code
switch -glob [HTTP::uri] starts_with

But that statement above returns me errors. I assume that can't be done or has to be done in some other format? Any help is greatly appreciated. Here's my existing code:

 

Code
when HTTP_REQUEST {
if {[HTTP::uri] contains "/read.pdf"} { 
       HTTP::redirect "https://www.main.com/menu" }

if {[HTTP::uri] starts_with "/Mypersonal/formula"} { 
       HTTP::respond 301 Location "https://www.main.com/colors.html" }  

switch -glob [HTTP::uri] {

"/page1" -
    "/page2" -
    "/page3" -
    "/index" -
    "/start" { pool orange }
    default { pool green }
}
}

Code

    Please try this:

    when HTTP_REQUEST {
    if { [HTTP::uri] contains "/read.pdf" } { 
        HTTP::redirect "https://www.main.com/menu" 
    } elseif { [HTTP::uri] starts_with "/Mypersonal/formula" } { 
        HTTP::respond 301 Location "https://www.main.com/colors.html" 
    } else {  
        switch -glob [HTTP::uri] {
            "/page1*" -
            "/page2*" -
            "/page3*" -
            "/index*" -
            "/start*" { 
                pool orange 
            }
            default { 
                pool green 
            }
        }
    }

    The -glob option allows you to use wildcards in the conditions, so a "starts_with" in a switch -glob would be a URI followed by a start "*".

    Seems like there might be a syntax somewhere that is causing error when I compile the iRule. This is the error I get:

    There is in fact a missing closing brace.

     when HTTP_REQUEST {
     if { [HTTP::uri] contains "/read.pdf" } { 
         HTTP::redirect "https://www.main.com/menu" 
     } elseif { [HTTP::uri] starts_with "/Mypersonal/formula" } { 
         HTTP::respond 301 Location "https://www.main.com/colors.html" 
     } else {  
         switch -glob [HTTP::uri] {
             "/page1*" -
             "/page2*" -
             "/page3*" -
             "/index*" -
             "/start*" { 
                 pool orange 
             }
             default { 
                 pool green 
             }
         }
     }
 }
