Subject Re: ATS teething issues
Date Sat, 22 Aug 2015 22:28:37 GMT
For #1, you need the following in your remap rules

map http://xxx/ http://yyy @plugin=/opt/ats/libexec/trafficserver/tslua.so
@pparam=/opt/ats/etc/trafficserver/sethost.lua @pparam=abc

That's because the sample lua script you have requires an extra parameter.
Without that, the lua script stated to quit right away without finish
initializing.

Thanks.
