HTTP::COOKIE not working as expected

Sorry... I misread your post. On 10.0.1, the cookie value seems to work:

 
 when HTTP_REQUEST { 
  
 HTTP::cookie insert name cookie1 value value1 
 HTTP::cookie insert name cookie2 value value2 
  
 if {[HTTP::cookie exists cookie1]}{ 
 log local0. "cookie1 exists" 
 } else { 
 log local0. "cookie1 does not exist" 
 } 
 if {[HTTP::cookie exists cookie2]}{ 
 log local0. "cookie2 exists" 
 } else { 
 log local0. "cookie2 does not exist" 
 } 
 log local0. "Cookie names ([HTTP::cookie names])" 
 foreach cookie [HTTP::cookie names] { 
 log local0. "\[HTTP::cookie value $cookie\]: [HTTP::cookie value $cookie]" 
 } 
 } 
 

: cookie1 exists

: cookie2 exists

: Cookie names (cookie1 cookie2)

: [HTTP::cookie value cookie1]: value1

: [HTTP::cookie value cookie2]: value2

Can you add logging to your iRule and post the results from HTTP::cookie exists "cookie_name" and HTTP::cookie value "cookie_name"?
