    <description>&lt;P&gt;@Greg-DB&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Is there a release note or anything for this feature change? I have notices a few thread in the forum related to this "Transfer-Encoding: chunked" change, and I have been affected by it as well. It would've been nice to get a heads up, if possible, for changes coming down the pipe. If not, a note after changes explaining what was changed would be helpful.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Dropbox stopped returning Content length in the response headers. Any reason as to why?&lt;BR /&gt;When I call this from C# code, I don't get the response.ContentLength();&lt;BR /&gt;&lt;A href="https://www.dropbox.com/s/a3lhvatmf7f6ys3/appv1.ipa?dl=1" target="_blank" rel="noopener"&gt;https://www.dropbox.com/s/a3lhvatmf7f6ys3/appv1.ipa?dl=1&lt;/A&gt;&lt;/P&gt;</description>

      <description>&lt;P&gt;even I am facing this issue. Has there been any recent change?&lt;/P&gt;</description>

      <description>&lt;P&gt;I understand you're programmatically accessing Dropbox shared links, and have been relying on the "Content-Length" header being set on responses.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Please note that Dropbox does not guarantee that the "Content-Length" HTTP response header will always be present on the responses for these URLs though. For example, when the server is using "Transfer-Encoding: chunked" for the response, "Content-Length" is omitted. While the Dropbox servers use the HTTP protocol, exactly which features they use may change over time. In this case, server updates were made recently to use 'Transfer-Encoding: chunked' for HTTP/1.1 requests to these.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I'm passing this along to the team as a request to revert to returning the 'Content-Length' response header, but I can't promise if or when that might be implemented.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Either way, you should update your client/code to support "Transfer-Encoding: chunked" and not assume the "Content-Length" response header will be present. Or, switch to HTTP/2, where the "Content-Length" response header should be present.&lt;/P&gt;</description>

      <description>&lt;P&gt;&lt;a href="https://www.dropboxforum.com/t5/user/viewprofilepage/user-id/1518580"&gt;@rdee&lt;/a&gt; Thanks for the feedback. This was not pre-announced as this encoding type is a part of the HTTP spec itself, and is expected to be handled by HTTP clients automatically, but I'll share this with the team.&lt;/P&gt;</description>

      <description>&lt;P&gt;Update: in order to temporarily accommodate clients that don’t properly support automatically handling “Transfer-Encoding: chunked”, we’re temporarily rolling back this change, so that these links will no longer use “Transfer-Encoding: chunked” and will instead return “Content-Length” on HTTP/1.1. We will begin rolling that out starting around 2/17. That will be in place until around 3/1. At that point, we will begin using “Transfer-Encoding: chunked” and no longer returning “Content-Length” on HTTP/1.1 again.&lt;/P&gt;
&lt;P&gt;&lt;BR /&gt;Going forward, please ensure that your clients are able to automatically handle both chunked encoding and non-chunked encoding automatically.&lt;/P&gt;</description>

      <description>&lt;P&gt;Update: we have extended the timeline and are planning to keep the current behavior until at least 3/14.&lt;/P&gt;</description>

      <description>&lt;P&gt;Update: the team has been able to complete some further updates to our infrastructure to be able to support the previous non-chunked behavior going forward indefinitely. That means that we plan to continue returning Content-Length (and not 'Transfer-Encoding: chunked') in the future and will not be reverting this on 3/14. (Regardless, for HTTP compatibility in general, we still recommend you make sure your HTTP clients support both types.) Hope this helps!&lt;/P&gt;</description>
