[jira] Resolved: (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 ]
Oleg Kalnichevski resolved HTTPCLIENT-929.
------------------------------------------
Resolution: Fixed
Fixed in SVN trunk
http://svn.apache.org/viewvc?rev=930558&view=rev
I looked at #relativize method but felt it was an overkill. I opted for a simpler and likely faster custom routine. Please review.

> Key: HTTPCLIENT-929
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-929
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 4.0.1
> Reporter: Ryan Stewart
> Fix For: 4.1 Alpha2
>
>
> 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:
