I want to parse an XML document that is on a different site. Everything works fine if I'm downloading it manually as an XML document, but if I want to get the data directly from the URL
$xml = file_get_contents ( "http://www.blueshop.pl/sklepy.aspx");
I get an error
Warning: file_get_contents (http://www.blueshop.pl/sklepy.aspx): failed to open stream: HTTP request failed!
What is the problem here? I understand from the fact that this ASPX page? Other XML documents from external web sites can be read without problems.
