Subject Re: Problems with a URL, can't connect (IE works for this URL)
Date Sat, 21 May 2005 10:12:08 GMT
Christophe,

You are aware that you are executing HTTP HEAD whereas IE or any other
browser usually uses HTTP GET to access a URL? 

GetMethod of HttpClient produces perfectly reasonable result:

[DEBUG] header - ->> "GET /rmhttp/downloadtrial/radio4/inourtime/rss.xml
HTTP/1.1[\r][\n]"
[DEBUG] header - ->> "User-Agent: Jakarta Commons-HttpClient/3.0-rc2
[\r][\n]"
[DEBUG] header - ->> "Host: downloads.bbc.co.uk[\r][\n]"
[DEBUG] header - ->> "[\r][\n]"
[DEBUG] header - -<< "HTTP/1.0 200 OK[\r][\n]"
[DEBUG] header - -<< "Date: Sat, 21 May 2005 11:09:12 GMT[\r][\n]"
[DEBUG] header - -<< "Server: RealServer[\r][\n]"
[DEBUG] header - -<< "Content-Type: text/xml[\r][\n]"
[DEBUG] header - -<< "Last-Modified: Thu, 19 May 2005 11:54:40 GMT
[\r][\n]"
[DEBUG] header - -<< "Content-Length: 1249[\r][\n]"

			<description>Does beauty really have a moral quality? And is it
inherent in things, or in the mind of the observer? How much influence
have Plato's ideas had on the history of aesthetics and what has been
said to counter or develop them?</description>
