MIME: updated type for js files to text/javascript. RFC 9239 changed recommended media type to text/javascript, and made application/javascript deprecated. According to httparchive.org data, as of 2023-01-01 javascript files are returned with the following types (type, total pages using the type, total requests with the type): application/javascript,11686643,218376911 text/javascript,9623206,76111177 application/x-javascript,4874976,28554156 The same data as of 2024-01-01: application/javascript,10563307,205156998 text/javascript,8429652,78523734 application/x-javascript,4197414,26277166 And as of 2024-08-01: application/javascript,10945376,216622264 text/javascript,8802358,102680806 application/x-javascript,4278134,28726895 This corresponds to text/javascript being used in 23.5%, 25.3%, and 29.5% of responses. That is, it is slowly gaining popularity. Still, application/javascript remains more popular for now. With this change, js files are now returned with the text/javascript type. Similarly, autoindex in jsonp format now also uses text/javascript. Additionally, text/javascript is added to the default charset_types list of the charset module. Since application/javascript is still more popular than text/javascript, application/javascript is also preserved in the default list for now.
