Redirecting iRule by URL depth

Hi,

try this one instead, just tested and found I had an issue with the previous one :

when HTTP_REQUEST {
    set lb_depth 0
    set lb_len 0
    set timeout 3600

    set path [string tolower [HTTP::path]]
    set depth [URI::path $path depth]

     define the depth of the path for hash calculation
    if { $depth < $lb_depth } {
        set depth_path [URI::path $path 1 $lb_depth]
    } else {
        set depth_path [URI::path $path 1 $depth]
    }

    set len [string length $depth_path]

     define the chars length to be processed for hash calculation
    if { $lb_len > 0 and $lb_len < $len } {
        binary scan [sha1 [string range $depth_path 0 $lb_len-1]] w1 key
    } else {
        binary scan [sha1 $depth_path] w1 key
    }

    persist uie $key $timeout
}
