"syntax error" at character '}'

Hello,

 

 

I am trying to add an iRule to our f5 and it loads just fine but I get an error when doing a config sync or b verify load.

 

The iRule works well and loads just fine, but this error is thrown ever time bigip.conf is loaded:

 

Reading configuration from /config/profile_base.conf.

 

rule limit_uri {

 

 

/config/bigip.conf: "syntax error" at character '}' in line 217

 

rule limit_uri {

 

 

/config/bigip.conf: "syntax error" at character '}' in line 217

 

 

 

Here is the iRule:

 

when RULE_INIT {

 

set ::rate 30

 

set ::window 300

 

set ::purge_interval 10

 

set ::last_purge [clock seconds]

 

array set ::hit_list {}

 

array unset ::hit_list

 

array set ::block_state {}

 

array unset ::block_state

 

array set ::hit_count {}

 

array unset ::hit_count

 

}

 

when HTTP_REQUEST {

 

if { [matchclass [string tolower [HTTP::path]] ends_with $::limit_uris] } {

 

set current_time [clock seconds]

 

set request_id "[HTTP::host]_[expr { int(1000000 * rand()) }]"

 

set ::hit_list($request_id) $current_time

 

set window_start [expr $current_time - $::window]

 

if { not [info exists ::block_state([HTTP::host])] } {

 

set ::block_state([HTTP::host]) 0

 

set ::hit_count([HTTP::host]) 0

 

}

 

if { [expr $current_time - $::last_purge] > $::purge_interval } {

 

set ::last_purge $current_time

 

set count 0

 

foreach { request_id request_time } [array get ::hit_list [HTTP::host]*] {

 

if { $request_time < $window_start } {

 

unset ::hit_list($request_id)

 

} else {

 

incr count

 

}

 

}

 

set ::hit_count([HTTP::host]) $count

 

}

 

if { $::hit_count([HTTP::host]) > $::rate } {

 

HTTP::respond 503 content "Page LimitedThis page is being limited due to excessive use. Please try again later"

 

if { $::block_state([HTTP::host]) == 0 } {

 

log local0. "Started blocking [HTTP::host]"

 

set ::block_state([HTTP::host]) 1

 

}

 

} elseif { $::block_state([HTTP::host]) == 1 } {

 

log local0. "Stopped blocking [HTTP::host]"

 

set ::block_state([HTTP::host]) 0

 

}

 

}

 

}
