if { (not [matchclass [string tolower [HTTP::uri]] starts_with $::LegacyExceptions])

 

and ([matchclass [string tolower [HTTP::uri]] starts_with $::LegacyPaths]) } {

 

 

checked for matchclass != exceptions and == LegacyPaths and forward to Legacy_http_pool

log local0. "*****DEBUG SNAT applied"

 

 

snat 172.23.0.60

 

pool Legacy_http_pool

 

 

HTTP::redirect http://www.google.com

 

 

} else {

 

when uri matches admin in Literatum check for source ip

 

if { [HTTP::uri] starts_with "/admin"

 

and (not [matchclass [IP::remote_addr] equals $::Admin]) } {

 

Literatum path for admin uri but not internal IP

 

log local0. "External IP ([IP::remote_addr]) attempting to access admin path ([HTTP::uri])"

 

HTTP::redirect http://redirect.com/404.html

 

} else {

 

pool Stage_http_pool
