Migration tomorrow from v9 to v11 - cache

I am doing a migration from an older version (v9) to a new one (v11) shortly and I want to know as to whether or not this iRules will work from v9. I know "matchclass" has been deprecated inV10 and v11 and I must replace the matchclass Command in iRules with the "class match" Command. Do you think I need to change anything in this Irule ? Thank you for your help

 

Irule CACHE iRule is:

when HTTP_REQUEST {

 

set host [HTTP::host]

 

set uri [HTTP::uri]

 

set domi [substr [HTTP::host] 3 80]

 

set ip [IP::client_addr]

 

set expire_content_time [findclass [HTTP::uri] $::class_cacheable_pages " "]

 

if { ($expire_content_time eq "") } { set expire_content_time [findclass [string tolower [string range [HTTP::path] [string last . [HTTP::path]] end]] $::class_cacheable_files " "] }

 

if { ([matchclass [HTTP::path] starts_with $::class_no_cacheable_pages]) } { set expire_content_time "" } }

 

when HTTP_RESPONSE {

 

if { [HTTP::cookie exists "PHPSESSID"] } { set cookieDomain [HTTP::cookie domain "PHPSESSID"] if { ($cookieDomain starts_with "www") or ($cookieDomain eq "") } { HTTP::cookie

domain "PHPSESSID" "$domi" }

 

}

if { [HTTP::status] == 404 } {

 

if { $host starts_with "private" } {

 

log -noname 10.10.10.50:514 local4.info "ERROR 404 $uri"

 

return }

 

if { ($host contains "ecd2016") or ($host contains "mps2015") or ($host starts_with "old") or ($host starts_with "ecd2016") } { return }

 

HTTP::redirect "http://www.TOTO.org/error.php"

HTTP::respond 404 content $::error_404 "Content-Type" "text/html" return }

 

if { $ip equals "10.10.10.31" } { HTTP::header insert "serverName" [LB::server addr] }

 

if { $expire_content_time ne "" } {

 

HTTP::header replace "Cache-Control" "max-age=$expire_content_time"

 

HTTP::header replace "Expires" "[clock format [expr ([clock seconds]+$expire_content_time)] -format "%a, %d %h %Y %T GMT" -gmt true]"

 

}

 

else {

 

HTTP::header replace "Cache-Control" "max-age=60"

 

HTTP::header replace "Expires" "[clock format [expr ([clock seconds]+60)] -format "%a, %d %h %Y %T GMT" -gmt true]" } }
