--------------------------------------
Sorry for my bad English.
You can input multiple URLs separated new lines in the textarea of the four
forms below of Cache Inspector:
* Delete url
* Regex lookup
* Regex delete
* Regex invalidate
How to reproduce the problem:
1. Enable the debug log and add cache_inspector to debug tags.
/etc/trafficserver/records.config
CONFIG proxy.config.diags.debug.enabled INT 1
CONFIG proxy.config.diags.debug.tags STRING http.*|dns.*|cache_inspector.*
2. Input the following two lines in the Regex invalidate form.
http://.*\.js
http://.*\.jpg
3. See /var/log/trafficserver/traffic.out
/var/log/trafficserver/traffic.out
