Asp.Net CDN Minified JQuery Not Gzipped?

Does anyone know if there is a reason why the minified versions of the jQuery files on the Asp.Net content delivery network are not gzip compressed? The non-minified versions are properly compressed.

Examples:

http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.unobtrusive-ajax.js (GZipped) http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.unobtrusive-ajax.min.js (Not GZipped)

If I look at the Google CDN, the minified files are also gzipped. Unfortunately they are not offering jquery.unobtrusive-ajax, jquery.validate, or jquery.validate.unobtrusive.

Solution

  • Not sure what was going on, but now the files are showing gzipped. As mentioned in one of my comments, it seemed to change when I went from one I.P. to the other.
