我需要在每次请求的时候做一些频率拦截只能在service 块写、

怎样才能每次请求只执行一次呢？我试了access_by_lua rewrite_by_lua 都不行、

Hello!

尝试在你 server 级别的 rewrite_by_lua 的逻辑里，判断下当前请求是否是内部请求：

ngx.req.is_internal
syntax: is_internal = ngx.req.is_internal()
context: set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua*
Returns a boolean indicating whether the current request is an "internal request", i.e., a request initiated from inside the current nginx server instead of from the client side.
Subrequests are all internal requests and so are requests after internal redirects.
This API was first introduced in the v0.9.20 release.

Thanks 、That is ok

另外能帮看下 https://groups.google.com/forum/#!topic/openresty-en/e9RhKt159TY 这个问题吗、

ngx.shared 在 no memory 的时候 expired key 已经过期的key 不删除不释放 :-D
