[jira] Updated: (HTTPCLIENT-929) Request with two forward slashes
for path fails
[ https://issues.apache.org/jira/browse/HTTPCLIENT-929?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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:
