iRule Question

Hi everyone, this is my first time using Data Group lists and I'm having some trouble with the below iRule. Does anyone have any suggestions on what I might be doing wrong?

 

Also a summary as to what the iRule is doing. Basically if you are trying to go a URI other than one on the "approved" data group list, you get redirected back to the root level of the site.

 

when HTTP_REQUEST {

 

if { [[HTTP::uri] starts_with a_string] } {

 

pool some_pool

 

}

 

else { HTTP::redirect "https://somedomain.com/" }

 

}

    This should do the trick. Just make sure your DG is a string list and your /URIs go in the string field.

    when HTTP_REQUEST {
    if { [class match [HTTP::uri] starts_with "/Common/"] } {
        pool some_pool
    }
    else {
        HTTP::redirect "https://somedomain.com/"
    }
}

      probably want to [string tolower [HTTP::uri]] to make sure your matching is all lower case.

      Unfortunately it still seems like it isn't matching against the datagroup and forwarding all URIs on to the pool.

    Brad - looks like the iRule above has too many } but it would error when creating the irule so can i assume you've removed one of these.

    Anyway, what does your DG look like. I tested the irule above with the following DG and it worked just as Brad Parker suggested.

    Here's my DG

    ltm data-group internal uri_allowed {
    records {
        /test { }
    }
    type string
