js files are returned with MIME-type of application/javascript, which by default is not one of the MIME-types generally set up for Apache mod_deflate

[weyus]

All the .js or .min.js (bundle) files returned by AH appear to come back with the MIME-type of application/javascript.

My Apache configuration is currently not set up to compress these types of files.

1. Is application/javascript a preferred or more standards-compliant MIME-type for Javascript than text/javascript or application/x-javascript?

2. If so, is there any harm in me adding application/javascript to the list of MIME types available for compression by Apache? I can't imagine there would be since all of the other JS MIME types are in there, but I thought I would ask.

Many thanks.

Sorry I have not better answer but, it's time to update your Apache config, probable duplicate, some might still pass it as text/javascript but see here: http://annevankesteren.nl/2006/05/javascript-mime-type
