--- Comment #1 from Konstantin Kolinko <knst.koli...@gmail.com> --- (In reply to Alexander Veit from comment #0) > Ref.: > [1] https://datatracker.ietf.org/doc/draft-ietf-dispatch-javascript-mjs/17/ > [2] https://www.iana.org/assignments/media-types/media-types.xhtml#application Some notes. 1. The IETF document [1] is a draft, but looking at its "History" [3] tab, it has been approved. > 2022-03-02 - IESG has approved the document > 2022-03-02 - IESG state changed to Approved-announcement sent The document is currently in a queue [4] to be published. [3] https://datatracker.ietf.org/doc/draft-ietf-dispatch-javascript-mjs/history/ [4] https://www.rfc-editor.org/current_queue.php#draft-ietf-dispatch-javascript-mjs 2. The IETF Draft mentions (in "6.") that the HTML specification already uses "text/javascript" as the default media type. That essentially refers section "4.12.1.1 Processing model" of the HTML Specification. [5] [5] https://html.spec.whatwg.org/multipage/scripting.html#script-processing-model 3. Looking at the HTML specification, one can see the following text in section "4.12.1.2 Scripting languages" [6]: > Servers should use text/javascript for JavaScript resources. [6] https://html.spec.whatwg.org/multipage/scripting.html#scriptingLanguages 4. The IETF Draft also mentions a new file extension ".mjs" is being registered. 5. Apache Tomcat generally follows Apache HTTP Server in its mime-type mappings. One can see that the configuration file "conf/mime.types" in Apache HTTP Server project has not been updated yet. Both in the trunk version [7] (last updated in December 2020), and on the 2.4.x branch [8] (last updated 4 years ago) as well. [7] https://svn.apache.org/viewvc/httpd/httpd/trunk/docs/conf/ [8] https://svn.apache.org/viewvc/httpd/httpd/branches/2.4.x/docs/conf/ 6. Personally, it is odd to me to read that "text/javascript" is more popular than "application/javascript", despite RFC4329 [9] that suggested otherwise, despite all popularity of Apache HTTP Server and "application/javascript" being the default configuration. My guess is that "text/javascript" is popular as a value of the type attribute of <script> tag of HTML (not only thanks to HTML 5 specification, but the previous HTML 4 as well [10]), but hardly anyone cares what Content-Type is used when sending a js file over the wire. [9] https://datatracker.ietf.org/doc/html/rfc4329 [10] https://www.w3.org/TR/html401/interact/scripts.html Overall, I see that there are grounds to make the change. I would like to wait for the official publication of the document by IETF, and RFC4329 [9] being declared as obsolete. Also it looks that we can add a mime-mapping for "mjs" to be "text/javascript" at the same time. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
