if you go to http://www.sketchfemme.com using your browser you will get (view source):
<!doctype html>
<html>
<head>
<meta charset="utf-8"/>
<title>SketchFemme Feature of the Day</title>
.....
<link href="/featured.rss" rel="alternate" title="SketchFemme Feature of the Day" type="application/rss+xml" />
</head>
But from mac terminal if I execute this command:
curl sketchfemme.com -A "Mozilla/4.0" --trace-ascii - -L
I get back the xml content of the rss file.
I was expecting to see HTML using the curl command, why am I getting back XML?
Curl is adding
Accept: */*header. This is causing your site to return with the RSS. (I have no idea why it is doing this). If you try it without the Accept header, then it works as you expect.
