will rand() cause performance issue

Hi,Ryan

 

skewing is because I can't reset 3561 to 0 in the rule with rand()

 

I can only set it to

 

 

+-> HTTP_REQUEST 3563 total 0 fail 0 abort

 

| | Cycles (min, avg, max) = (0, 0, 0)

 

+-> HTTP_RESPONSE 168 total 0 fail 0 abort

 

and get

 

 

+-> HTTP_REQUEST 3563 total 0 fail 0 abort

 

| | Cycles (min, avg, max) = (0, 466582, 1446128)

 

+-> HTTP_RESPONSE 168 total 0 fail 0 abort

 

 

1:the reason I can't use default profile is besides this pool,under this VS ,there are 10 other pools which don't need persist

 

so I can only achieve this via irule,this VS dones't have default pool,only irule

 

 

1:I don't know how to optimize rand()

 

2:I don't know how to insert cookie and persist it in irule

 

 

pls help me
