Hi, I am working on a design to do load balancing for a cluster of servers based on URLs.
My URLs are for e.g - http://mydomain.com/request?type=xxx http://mydomain.com/request?type=yyy I want to do URL load balancing based on the 'type' attribute. Sp for type 'xxx' it can goto backend_farm_x and type 'yyy' it can goto backend_farm_y.. Can someone please help me what kind of rule is it it preferable - url_reg, url_sub, path_reg, path_sub? If anyone can point me to such samples rule, it will be useful. I starrted off with these rules but it didn't work - frontend myfrontend *:80 log global maxconn 25000 option forwardfor # acl acl_example1 url_reg /([a-z]+)/xxx/([a-z]+)/ # acl acl_example2 url_reg /([a-z]+)/yyy/([a-z]+)/ # acl acl_example1 url_reg (.*)xxx(.*) # acl acl_example2 url_reg (.*)yyy(.*) # acl acl_example1 path_sub xxx # acl acl_example2 path_sub yyy acl acl_example1 path_reg (\S+)xxx(\S+) acl acl_example2 path_reg (\S+)yyy(\S+) # acl acl_example1 path_reg xxx # acl acl_example2 path_reg yyy use_backend example1_farm if acl_example1 use_backend example2_farm if acl_example2 default_backend default_farm On the server logs, it falls to the default backend. I have tried all the combinations above. Thanks, Praveen.
