add flag to http header based on which pool is selected

There is an option to insert a header in the pool configuration in 4.x:

 

 

Header To Insert:

 

 

- client_addr

 

- client_port

 

- server_addr

 

- server_port

 

- ip_tos

 

- link_qos

 

 

The format for the variables is: ${variable}. So to insert the client IP address in the header you could use: ${client_addr}.

 

 

Unfortunately, none of these options allow you to specify the node address.
