NimbostratusHelp with Cookie Insertion
Hello,
Currently we're using the following on a vs,
when HTTP_REQUEST {
if { [HTTP:uri] starts_with "/clasee*"} {
pool class}
else {
pool main}
}
We need to add a cookie when request comes in from certain source IPs; we've tried this with no luck so far
when HTTP_REQUEST {
if { [matchclass [IP::client_addr] equals "$::class_ip"] } {HTTP::cookie insert name "class" value "class"}
elseif { [HTTP:uri] starts_with "/clasee*"} {pool class}
else {pool main}
}
Thanks for any help in advance

- The_BhattmanHi User 1115,
I think the issue might be in the logic of what are yo trying to do.
According to your iRule the logic works like this:
If client ip matches the class_ip datagroup, apply the Cookie Insert and then EXIT the iRule. (NOTE: It will not evaluate the rest of the iRule)
If client ip does not match the class_ip datagroup, and if the uri starts with "/clasee" then go to pool called class and EXIT the iRule. (NOTE: No Cookie Insert will be invoked)
If client ip does not match and your URI does not start with /clasee then go to pool main and EXIT the iRule. (NOTE: No cookie Insert will be invoked)
Is this logic you want?.

user1115_113077Bhattman,
Thank you for tte explaination and clearly that's not what we want.
We need to:
If the client matches the class_ip datagroup, apply the coookient insert AND continue to check the uri, if the uri starts with "/class" go to pool call class, if the uri does not start with "/class" go to pool main and exit the irule. (has cookie)
If the client does not matches the class_ip datagroup, check the uri, if the uri starts with "/class" go to pool cll class if the uri does not start with "/class" go to pool main and exit the irule. (no cookie)
We appreicate any help with any rule for the above logic, we're first time irule user.
Best regards,- The_BhattmanHi User1115,
In that case one of the ways you can do this is the following codes
This is for version 9.x.x
when HTTP_REQUEST {
Insert cookie if it matches the CLASS_IP datagroup
if { [matchclass [IP::client_addr] eq $::class_ip] } {
HTTP::cookie insert name "class" value "class"
}
Choose a pool based on URI
if { [HTTP:uri] starts_with "/clasee*"} {
pool class
} else {
pool main
}
}
OR Using a switch statement
when HTTP_REQUEST {
Insert cookie if it matches the CLASS_IP datagroup
if { [matchclass [IP::client_addr] eq $::class_ip] } {
HTTP::cookie insert name "class" value "class"
}
Choose a pool based on URI
switch -glob [string tolower [HTTP::uri]] {
"/clasee*" { pool class }
default { pool main }
}
}
If you are going to v10 then the code would like like the following
when HTTP_REQUEST {
Insert cookie if it matches the CLASS_IP datagroup
if { [class match [IP::client_addr] equals "class_ip" } {
HTTP::cookie insert name "class" value "class"
}
Choose a pool based on URI
if { [HTTP:uri] starts_with "/clasee*"} {
pool class
} else {
pool main
}
}
OR Using a switch statement for v10
when HTTP_REQUEST {
Insert cookie if it matches the CLASS_IP datagroup
if { [class match [IP::client_addr] equals "class_ip"] } {
HTTP::cookie insert name "class" value "class"
}
Choose a pool based on URI
switch -glob [string tolower [HTTP::uri]] {
"/clasee*" { pool class }
default { pool main }
}
}
I hope this helps
Bhattman - The_BhattmanHi User1115,
For debugging you can do the following:
This is for version 9.x.x
when HTTP_REQUEST {
Insert cookie if it matches the CLASS_IP datagroup
if { [matchclass [IP::client_addr] eq $::class_ip] } {
HTTP::cookie insert name "class" value "class"
log local0. "The Source IP: [IP::client_addr] matched. Inserting Cookie"
}
Choose a pool based on URI
if { [HTTP::uri] starts_with "/clasee*"} {
log local0. "The URL is [HTTP::uri] which is selecting pool class"
pool class
} else {
log local0. "the URL is [HTTP::uri] which is selecting pool main"
pool main
}
}
OR Using a switch statement
when HTTP_REQUEST {
Insert cookie if it matches the CLASS_IP datagroup
if { [matchclass [IP::client_addr] eq $::class_ip] } {
log local0. "The Source IP: [IP::client_addr] matched. Inserting Cookie"
HTTP::cookie insert name "class" value "class"
}
Choose a pool based on URI
