I have to write HAProxy cofiguration for testing an app. As i am new to HAProxy and not using frequently, need some help which ACL or configuration directive should be used. Following is the logic i have to apply.
Following is the Logic to apply:
A. frontend path
ACL check the path and redirect to backend path_AppName if path contains AppName
Here i think following can be used: 1. acl host_appName path_sub appname use_backend pool_appname if host_appname 2. acl url_appname path -i -m beg /appname/ use_backend backend_pool_appname if url_appname Which will be good?
B. frontend AppName
ACL check if cookie is set, if it exists then redirect to corresponding AppName_x backend
ACL Check if param is set, if it exists then redirect to corresponding AppName_x backend
Else go to AppName_default backend
I am unaware of this part. Which ACL will be helpful?
C. backend AppName_default
load balance to 1 instance and set cookie in response
Note: App uses serverid as cookie. Can we use “appsession” in this case?
D. backend path_AppName
redirect to frontend AppName
E. Backend AppName_x
keep session affinity
