I just upgraded a legacy application from Tomcat 7 to Tomcat 9. It's
deployed as a war file. I'm facing a weird issue with audio files playback.

When loading a page that contains an audio file. First time Tomcat returns
404 error but if reloading the page, audio file is loaded properly and no
error from Tomcat.

I'm using html 5 audio control to display the file.

All other static resources(images, css and js files) are working without
any issues. Only audio files are having this issue.

I enabled the logs for DefaultServlet in Tomcat. Follwong is the log entry
when I try to open the audio file first time. I can see 404 being returned
from server in Chrome dev tools.

Following is the log for 2nd attempt. This time audio is available and
playable in browser. *09-Mar-2024 20:13:00.371 INFO

Are the audio files generated dynamically on request?

Here is the audio control code:

<div id="audioContainer" style="height:65px; width:100%;
visibility:visible; ">
    <div id="jobAudio" style="height:45px; width: 100%; left:0px; bottom:0;"

       <audio controls controlsList="nodownload" style="width: 100%;" >
         <source src="/wav/2B916004DFE94FA40446429E1671C893_0001053.mp3"
type="audio/mpeg" >
       </audio>
    </div>
</div>
I've tried relative path and full path but result is the same in both cases.

I've spent days trying to solve this but no luck :(

I would really appreciate any guidance to solve this issue.

Thanks!
