<div style="font-family:Helvetica,Arial;font-size:13px; ">I think serving files via FileHandler or via callback-registry is pretty much the same performance wise. If you use the callback-registry then the mechanisms that lead to the callback-registry already
take care of the session-specific stuff. Having a file handler at /files typically allows for using an apache for serving files. In that case however you cannot use the session-key, so your new file-handler will not help much performance wise.</div>

sorry for my late reply. For some reason, your answer was moved to my <br>
spam folder and I just found it there between lots of pharma and crypto <br>
tips...<br>
<br>
While I see where you are headed with this, I wonder if there are <br>
differences between the approaches. I have the feeling a separate <br>
WAFileHandler might have the advantage of being more decoupled from the <br>
components that consume/refer/use files. And I wonder if a separate <br>
WAFileHandler might decouple things a little more, like allowing for <br>
parallel execution of requests?<br>
