<p dir="auto">It would be nice if you could add an issue template to the repository.</p>
<p dir="auto">I have a setup where one route behaves as a form processor for various forms. Under the normal circumstance of uploading an audio file... (mp3)... I would be using "flask.request.files" to process this file.</p>
<p dir="auto">But what if I do not have any forms on the site that upload files... what I have noticed and provided a file for to duplicate the issue ... is in the event of an audio file POST upload to a form processor that does not have a control to process files... ie "flask.request.files".... the "flask.redirect([route])" fails...</p>
<p dir="auto">Line 61 of the sample file is purposely left commented out...to demonstrate the redirect failure... by removing comment and enabling ..."posted_files = flask.request.files" .... the redirect magically works again...</p>
<p dir="auto">There seems to be an issue in the fact that an audio file is being posted... the same test run with images file formats entered into line 40.....ie.... accept=".jpg, .png" do not effect the redirect...</p>

<p dir="auto">In case anyone is interested.... I'm running Flask v1.0.2 on Python v3.6.3</p>
