hello. This is jay and it’s been 2 weeks since I started to work on
traffic server.
I’m working on a throttling plugin. can I assign the plugin to a specific
domain like remap plugin?
For example, a throttle plugin serves www.exampleA.com and another plugin
serves www.exampleB.com.
A throttling plugin originated from null-transform plugin works well. i
tried to implement a throttling in remap plugin but it doesn’t work.
I traced log files and there was a difference in ending.
The ending of normal throttling plugin log file is…
