Ryan Stewart updated HTTPCLIENT-929:
------------------------------------
Description:
The following code demonstrates the problem:
DefaultHttpClient client = new DefaultHttpClient();
client.execute(new HttpGet("http://www.google.com//";));
When a request is made, the DefaultRequestDirector invokes rewriteRequestURI().
I don't fully understand why this method does what it does. For a non-proxied
request, it attempts to render the URI to a relative URI. In doing so, it tries
to create a relative URI whose content is "//". Per RFC 2396 section 5
(Relative URI References), a relative URI that begins with "//" is a
network-path reference, and the "//" must be immediately followed by an
authority. Therefore, while "http://www.google.com//"; is a valid absolute URI,
"//" is not a valid relative one. The resulting exception:
