Redmine

Redmine by default, does something bad: it uses (in certain places only) the .js file extension for files that contain user content. ie files that should not be cached.

A small change should be made, to stop using the .js extension in these specific places.

Because:
Many Redmine users, configure Apache/Nginx to cache-in-the-browser all static files, such as .css and .js.
And the obvious config: is to look for files name *.js or *.css.

But those users will experience problems, that they then post here about (see list at the end).
It is a hard thing to diagnose -because the connection between the apache.nginx change and these specific, local problems: is not obvious.

It happens alot, so fixing this will save many people pain.

When people add a Nginx or Apache config to cache all .js files - at first everything seems to work... but then a day or more later they will notice a problem: it will happen on one of a few specific places

a) Click 'edit' on an existing journal in an issue

(the js file created is eg 24174.js where 24174 is the journal number: the AJAX call is:

- GET https://redmine.xyz.com/journals/edit/24174.js

b) Uploading a file to an Issue

Having selected the file in the Browse button: this file is called, (which contains the image file being sent to the server)

- POST https://redmine.xyz.com/uploads.js?attachment_id=1&filename=my-file-to-upload.png
