Cache URL plugin configuration help required

[Muhammad Faisal <fa...@yahoo.com>]

Hello,
I have configured the cacheURL plugin the daigs show plugin loaded but i 
dont see any log file in the logs folder. The contents of cacheurl.conf 
are as follows:
*
**diags shows plugin loaded:*

[Feb  4 01:02:54.765] Server {0x2ae87e53d340} NOTE: <Plugin.cc:84 
(plugin_load)> loading plugin '/usr/local/libexec/trafficserver/cacheurl.so'
[Feb  4 01:02:54.792] Server {0x2ae87e53d340} NOTE: <Main.cc:1794 
(main)> traffic server running
[Feb  4 01:03:16.633] Server {0x2ae885615700} NOTE: <Cache.cc:1045 
(cacheInitialized)> cache enabled

*target file for example:*
http://cw003.gear3rd.net/files/videos/2016/02/03/14544886014a97b-360.mp4

The below regexp is correct i wonder?

[root@ATS trafficserver]# cat cacheurl.config
http://tune.pk/video\/* http://ts.tune.pk/$1
http:\/\/w+\.gear3rd\.net\/files/videos/\d{4}\/\d{2}/\d{2}\/(\\w+\-\\w+\.mp4) 
http://atvid.gear3rd.net/$1&$2
[root@ATS trafficserver]#

The files are not being cached at all the above configurations are 
correct? How to enable log for cacheurl plugin?

I have referred to below guide by translating it in English:
