This plugin works for me. I have some questions. After modifying the cacheurl.config file, I must restart traffic_server or use "traffic_line -b".
1. Will "traffic_line -b" block the requests during "Bounce local traffic_server"? 2. How can I improve the plugin if I want the plugin to reread the config files when "traffic_line -x"? 2011/3/24 Mark Harrison <[email protected]> > > This meas that evey modified url you want to cached you have to write > into > > this file? > > > For example, i have a url like http://example.com/a.jpg?id=xxx, if i > want > > cache this object, does mean i have to wirte patterns/replacements > > in cacheurl.config? > > Yes, the file specified a list of URLs and what you want the cache key > to be.
