Problem this snippet solves:
Webbots, you can't live with them, you can't live without them... This iRule determines if a webbot is accessing your systems and assigns them to a lower priority resource. The first example includes the bot list inside the rule and uses the switch statement to find a match.Code :
when HTTP_REQUEST { switch -glob [string tolower [HTTP::header User-Agent]] { "*scooter*" - "*slurp*" - "*msnbot*" - "*fast-*" - "*teoma*" - "*googlebot*" { # Send bots to the bot pool pool slow_webbot_pool } default { # Send all other requests to a default pool pool default_pool } } } ### or if you prefer data groups ### ---- String Class ---- class bots { "scooter" "slurp" "msnbot" "fast-" "teoma" "googlebot" } ---- iRule ---- when HTTP_REQUEST { if { [matchclass [string tolower [HTTP::header User-Agent]] contains $::bots] } { pool slow_webbot_pool } else { pool default_pool } }
Tested this on version:
10.0By default the bots can access or I have to create this small snippet in order to allow the bots access??
