Need help with an iRule to match multiple URI and redirect the http request to a pool

Thiyagu I found a few curled brace errors and some - in the incorrect location but those have been corrected. I added in a variable to utilize instead of reading directly from the HTTP header when matching on the switch statement. The last bit is I used this style guide that another user created if you would like to give it a once over when you have a moment.

Here is the iRule that should function the way you described.

when CLIENT_ACCEPTED priority 500 {

    set DEFAULT_POOL [LB::server pool]

}

when HTTP_REQUEST priority 500 {

    set URI [string tolower [HTTP::uri]]

    switch --glob ${URI} {
        "/next/x1/*" -
        "/next/x2/*" -
        "/next/x3/*" {
            pool POOL_NEXT_X
        }
        "/next/y1/*" -
        "/next/y2/*" {
            pool POOL_NEXT_Y
        }
        "/next/a1/*" {
            pool POOL_NEXT_A
        }
        "/next/b1/*" {
            pool POOL_NEXT_B
        }
        "/next/c1/*" {
            pool POOL_NEXT_C
        }
        default {
            pool ${DEFAULT_POOL}
        }
    }

}
