## Current behavior:
<!-- Describe how the current features are insufficient. -->
No ability to force asset refetch, only refresh.
## New behavior:
<!-- Describe how the feature would improve Traffic Control -->
A new feature will be added to the ATS regex_revalidate plugin to allow refetch in addition to just refresh.
This is based on ATS PR: https://github.com/apache/trafficserver/pull/6455
This new addition is supported to the regex_revalidate.conf file:
```
http://origin\.tld/images/foo\.jpg 1447483647 MISS
```
the keyword "STALE" may be also be used or left off for the normal regex_revalidate behavior (the next 2 are equivalent):
```
http://origin\.tld/images/foo\.jpg 1447483647
http://origin\.tld/images/foo\.jpg 1447483647 STALE
```
## Minimal reproduction of the problem with instructions:
<!--
If you can illustrate your feature request better with an example, please
provide the *STEPS TO REPRODUCE* and include the applicable TC version.
If not, feel free to delete this section.
-->
## Anything else:
<!--
e.g. additional context, related issues, suggestions about how to approach (feel
free to delete this section)
-->
If possible there should be a safety around this. Worst case behavior of this could result in the refetch of an entire library and not just refreshes. Perhaps rules can be made as stale and then "promoted" to MISS by an operator. Any rule that is switched between MISS and STALE is reset and treated as fresh by the regex_revalidate plugin.
