<br />
I am being required to setup IIS with request filtering to allow only specified file name extensions. &nbsp;I have the development site working with the extensions I have selected, but one JQuery stylesheet seems to be blocked (jquery-ui-1.8.11.custom.c<wbr />ss) with a 404.7 that is supposed to be the response when the extension is not in the allowed list. &nbsp;All other CSS files load fine.<br />
<br />
If I check &quot;Allow unlisted file name extensions&quot; everything works fine. &nbsp;The odd thing is that even though I have not specified CSS as an allowed file name extension, all my CSS files load except this one. &nbsp;If I add the CSS extension as allowed and uncheck the &quot;Allow..&quot; checkbox, my UI turns to trash like none of the CSS is being loaded event though none of the CSS requests are showing up as being denied.<br />
<br />
Has anyone else encountered this issue?
