Can somebody help me understand the below Irules for Secure Cookies,

Hi, Find the below details. Please correct me if any thing wrong.

 ltm rule SPOG-Secure-Cookies --> Name of irule
{ partition SKP when HTTP_RESPONSE --> Partision name SKP, where iRule stored
{ set myValues [HTTP::cookie names] ---> storing cookie value in "myValues" varible
 foreach mycookies $myValues ---> passing 'myValues' value in mycookies one by one through loop
{ HTTP::cookie secure $mycookies enable --> enabling cookie in browser
} } }


ltm rule SPOG-Domain-Cookies-IMC.com --> Name of irule
{ partition SKP when HTTP_RESPONSE   --> Partision name SKP, where iRule stored
{ log local0. "[IP::client_addr]:[TCP::client_port]: Pre Set-Cookies: [HTTP::header values Set-Cookie]" --> log         
message "client IP:port": Header cookie values
 Check if the persistence cookie exists in the response 
if {[HTTP::cookie exists "PD-L-SESSION"]}   ---> Checks cookie value
{  set the domain attribute on the persistence cookie 
HTTP::cookie domain "PD-L-SESSION" ".ironmountainconnect.com"  --> adding cookie value in 
"ironmountainconnect.com"
log local0. "[IP::client_addr]:[TCP::client_port]: Modified domain on PD-L-SESSION" }  --> log message "client 
IP:port" Modified domain on PD-L-SESSION"
if {[HTTP::cookie exists "PD-L-LAT"]} ---> Checks cookie value
{  set the domain attribute on the persistence cookie 
HTTP::cookie domain "PD-L-LAT" ".ironmountainconnect.com" --> adding cookie value in "ironmountainconnect.com"
log local0. "[IP::client_addr]:[TCP::client_port]: Modified domain on PD-L-LAT" } --> log message "client 
IP:port":Modified domain on PD-L-LAT"
log local0. "[IP::client_addr]:[TCP::client_port]: Post Set-Cookies: [HTTP::header values Set-Cookie]" } } --> 
log message": Post Set-Cookies: PD-L-LAT"
