+++ This bug was initially created as a clone of Bug #1283304 +++

Description of problem:
There is rather long initial loading time for business central after logon - might not be visible too much on localhost or local network as it's rather fast but is really visible on slower networks.
Problem is caused by disabled caching of resources (*.cache.js) while they are perfectly cacheable.

when looking at network trace from the browser after logon you can notice hat every time around 7 MB js file is downloaded from the server while it should be downloaded only once.

Version-Release number of selected component (if applicable):

How reproducible:
open network trace in the browser (like Chrome) and logon to business central - look at cache.js file being always downloaded instead of being served from cache after first use.

Steps to Reproduce:
1.
2.
3.

Actual results:
cache.js files are downloaded every time user logon

Expected results:
cache.js files should be downloaded only once

Thank you for identifying this!
Turns out this actually becomes important in two use cases:

1) on-line training: Student lab environments for RHT's BPM enablement course (OPEN and SkillsExchange) is hosted in the cloud. First impression for these students brand new to BPM Suite is the initial log into their remote biz-central web app in the cloud. We instruct them to be patient but there is still a high temptation to press the refresh button in their browser as they wait for what turns out to be a 7MB download.

2) partners / customers who have shared BPM Suite dev / test environments in their private cloud. We are seeing more of this. Often times their private network is not great.

Don't want to hijack this BZ but related: would be nice to have a javascript widget that shows real-time download status. Current status widget along with browser status (http://i64.tinypic.com/293bll3.jpg ) is OK but doesn't indicate how much of the download remains. Sorry, not sure if an off-the-shelf js widget that can do this even exists.

Another related topic: are the BPMN2 process designer javascript libraries configured to automatically get cached ?
