Minimal nginx conf to split get/post requests. Interesting idea for master-slave replication balancing where GET v.s. POST is load-balanced by nginx, presumably to different backend servers that are configured to talk to either a slave or a master. This won’t deal very will with replication lag though—you really want a user’s session to be bound to the master server for the next few GET requests after data is modified to ensure they see the effects of their updates. UPDATE: Amit fixed my complaint with a neat hack based around a cookie with a max age of 10 seconds.
