@stephenw10 no it is not a bug. That is me playing with this Squid version 3 storeID program below. I was turning on debug to log my files the second I did that it was throwing errors, I learned how to spell true. hahah
"“Store ID” is another name for the Squid cache key. By default, store IDs are computed by Squid so that different URLs are mapped to different store IDs. This feature allows the proxy admin to specify a custom store ID calculation algorithm via a helper program. It is usually used to assign the same store ID to transactions with different request URLs. Such mapping may reduce misses (i.e., increase hit ratio) when dealing with CDN URLs and similar cases where different URLs are known to point to essentially the same content.
Store ID violates HTTP and causes havoc if URLs pointing to different content are incorrectly mapped to the same Store ID. A Squid admin lacks control over URL-to-content mapping used by external CDNs and content providers. Even if the initial reverse engineering of their URL space is successful, maintaining the Store ID helper correctness is usually difficult because of sudden external mapping changes" (wiki.squid-cache.org/).

This is a CLI application made for PfSense and Squid 3
the idea is to use the already installed php in pfsense to do
the storeid_helper.
has of PfSense 2.2.6 php is on version 5.5.30 and Squid 3.4
Altough php has a bad reputation for being a continuous running application
it has become more and more stable since version 5.5
now with version 7.0 it is not only stable has has many performance improvements
that surpass most comon scripting languages.
So there is no problem with php running this.
Usage you can call out the script with many rewrite files to it or folders containing
rewrite rules with .conf termination.
inside the file it must have a hard tab between the match rule and and internal squid resolve

I am trying to get better dynamic cache hits.

Have you played with this ever? Again it should say refresh and not hit right?
The wiki status codes are confusing also.
