Hi Chan,
1.We had ATS 6.2 in Centos 6
2.Remap rules looks like below :
# DO NOT EDIT - Generated for edge1 by Traffic Ops (https://x.x.x.x) on Wed

map http://x.x.x.x:8082/ http://x.x.x.x/ @plugin=header_rewrite.so
@pparam=dscp/set_dscp_32.config @plugin=header_rewrite.so
@pparam=hdr_rw_live.config @plugin=background_fetch.so @pparam=bg_fetch.config
@plugin=collapsed_forwarding.so @plugin=tslua.so @@pparam=lua_test.lua
map http://x.x.x.x:8082/ http://x.x.x.x/ @plugin=header_rewrite.so
@pparam=dscp/set_dscp_0.config @plugin=background_fetch.so
@pparam=bg_fetch.config @plugin=collapsed_forwarding.so @plugin=tslua.so
@@pparam=lua_test.lua
note: I tried to given entire path in @@pparm syntax like
@@pparam=/opt/trafficserver/libexec/trafficserver/test_lua.lua
3.Lua Script looks like :
function cache_lookup()
local cache_status = ts.http.get_cache_lookup_status()
if cache_status == TS_LUA_CACHE_LOOKUP_HIT_FRESH then
print('hit')
else
print('not hit')
end
ts.http.set_cache_lookup_status(TS_LUA_CACHE_LOOKUP_MISS)
end
function do_remap()
ts.hook(TS_LUA_HOOK_CACHE_LOOKUP_COMPLETE, cache_lookup)
return 0
end
4.yes I did curl method only .

Subject: Re: How to use lua plugin and Scripts in Traffic server ?
A few things
1) What version of ATS are you on? 5.3.x ?
2) Can you show how your remap rules looks like?
3) you use the example lua script? if not, what is written in your script?
4) how do you test that? curl a url that goes against your machine?
5) Any messages in traffic.out / error.log / diags.log that is of interest ?
Thanks.
Kit
