Specifically I have a web application who’s source I can’t change, it’s not returning a specific Content-Type header and I’d like to start utilizing compression based on the mime-type. Durning my investigation I created a trivial web app for testing but was unable to get the mime-type specified in the mime-mapping applied to requests sent to the specific extension. This was with Tomcat 8.0.33. The details can be found below or at the stack overflow post here: http://stackoverflow.com/questions/42261607/tomcat-8-0-mime-mapping-co ntent-type. Just so you know, the mime-mapping only applies to resources served by the DefaultServlet. If the application is accepting a request to e.g. /my-file.txt, then the content-type isn't automatically being set to "text/plain" by Tomcat... it's up to the servlet to do that. The Mime-Mappings are available to servlets, but it's pretty rare for a custom servlet to bother actually using them. I wasn’t aware there was a servlet in-between simple requests like you stated. But that makes perfect sense. As noted in the SO post, I can see that StandardContext:addMimeMapping() is being called with my specific mapping during initialization. But I’m never seeing the backing mimeMappings called from there. I’ve seen quite a few online posts on this topic but can’t seem find any official documentation for 8+. Is this feature something that’s still supported? If so, is there something I’m overlooking in my test or configuration? Any light you guys can shine on the subject would be greatly appreciated. Thanks!

Hello There!== Info: Curl_http_done: called premature == 0 == Info: Connection #0 to host localhost left intact Yup: you are making a request to a custom servlet that doesn't do anything with the MIME mappings. You said you don't want to modify the source... what about *adding* to it? Would it be okay to write a Filter and add it to the configuration of the application? That is a very easy thing to do, and you can add whatever headers you want for whatever reason. Yep, a filter will be the next step. Honestly that’s the behavior I’m describing anyway. My initial hope was to keep the changes limited to Tomcat configuration but if that’s not possible that’s cool. Since it seems like a pretty common filter, is anyone aware of an existing implementation? I know it’s pretty trivial but no sense in rewriting the wheel if it’s already out there. Thanks!
