This servlet always minifies the response.

After some stress tests the result is a high consume of memory increasing the CPU times of the garbage collector, and impacting to other requests and the performance in general.

 

To test it:

Steps to Reproduce:

1. Start a server
2. With a navigator, open the dev-tools and look at the network tab, and load the home.
3. Refresh the home.

 

Actual Results:

js_loader_modules file is never cached.
Size: X KB

 

Expected Results:

Second requirement to js_loader_modules should be served as a cached resource.
Size: from memory cache
