I am trying to make an iRule that drops a request that is not destined for any of 4 different directories. Here is what I have so far, which hasn't been working:
when HTTP_REQUEST {
if { not [HTTP::uri] starts_with "/dir1" and
not [HTTP::uri] starts_with "/dir2" and
not [HTTP::uri] starts_with "/dir3" and
not [HTTP::uri] starts_with "/dir4"} {
drop
}
}
What am I doing wrong? Thanks!

when RULE_INIT {
array set ::valid_dir {
/dir1
/dir2
/dir3
/dir4
}
}
when HTTP_REQUEST {
if { ![matchclass [string tolower [HTTP::uri]] starts_with $::valid_dir] } {
discard
}
}

TCL error: Rule url-protection - can't read "::valid_dir": variable is array while executing "matchclass [string tolower [HTTP::uri]] starts_with $::valid_dir"
Thanks for your help.

class valid_dir {
"/dir1"
"/dir2"
"/dir3"
"/dir4"
}
when HTTP_REQUEST {
log "Valid directories: $::valid_dir"
if { not [matchclass [string tolower [HTTP::uri]] starts_with $::valid_dir] } {
discard
}
}
Thanks for the help.

Could someone please explain the meaning or concept of "$::" after keyword starts_with.
Thanks,

Altostratussure, in that context it's referencing a datagroup, in later versions of 9.4 and all 10.x versions, you should remove the $:: as it demotes from CMP. The $:: can also reference a global variable set in RULE_INIT event.
Has anyone done a sweep of wiki examples that specify $:: and changed them?
