custom dynamic feed urls don't work

[AndresClari]

I was trying to add the feed for ATP.fm podcast, but got the error:

Please check that the feed is correct and that you have a network connection.

Steps to reproduce:
- Click Add Podcast Feed
- Enter the feed url
- http://atp.fm/episodes?format=rss

Expected behavior:
- Parse the content of the url an add the feed

* Seems that the parser is trying to verify the feed based on the url format, while the contents are good in this case, the url seems to be marked invalid.

Relevant Software:
- Elementary OS Freya beta with latests updates applied

I don't think this is a bug. This is only with this particular url. For some reason it provides a valid response when you put it in your web browser.

You can see the response vocal is getting on http://onlinecurl.com/. Oddly enough the response is correct when I use curl in my terminal.

The headers are:
HTTP/1.1 403 Forbidden
Date: Sat, 06 Jun 2015 20:51:06 GMT
Content-Type: text/plain; charset=ISO-8859-1
Content-Length: 11
X-ContextId: 7h9AFpoz/ELuEWBeK
X-Via: 1.1 ny1-prod-echo012
X-ServedBy: 10

The body is:
Forbidden.

I did some debugging in vocal and it seems to be getting the same result.

I agree with Kyle, I don't think this is a problem in Vocal, but instead with the URL.
