Dear Wasong:
I am sorry that the codes are ulgy enough, and less comments.
Now, in my implement, I only support 255 content types.
the rule is file ext. match such as *.htm will redirect to
server A and *.gif will redirect to server B.
A type of content means a service in LVS.
A special type 0xff, means not match any contents.
At first, a syn packet comes to load balance, and it will match
a service(0xff) , and redirect it to back end.
After three-way handshae, client sends a packet with HTTP header,
and the load balancer parses the header to find out the content
type. And then, It find out a service that serives the content.
If the dest. is the same as pervious back-end, the packet will
be sent to that back-end. otherwise,the packet will be sent to
a new server that services the content.
........................................
@ @~ my english is poor. I will write down the key idea in my
paper soon.
sorry again.
