The credentials in the URL are NOT for the proxy server, but for the FTP server. The credentials for the proxy server are sent via HTTP-Headers. When requesting a document on a site via a proxy, the absolute URI should be used, i.e. a URI WITH credentials. See 5.1.2 of RFC2616: 5.1.2 Request-URI The Request-URI is a Uniform Resource Identifier (section 3.2) and identifies the resource upon which to apply the request. Request-URI = "*" | absoluteURI | abs_path | authority The four options for Request-URI are dependent on the nature of the request. The asterisk "*" means that the request does not apply to a particular resource, but to the server itself, and is only allowed when the method used does not necessarily apply to a resource. One example would be OPTIONS * HTTP/1.1 The absoluteURI form is REQUIRED when the request is being made to a proxy. The proxy is requested to forward the request or service it from a valid cache, and return the response. Note that the proxy MAY forward the request on to another proxy or directly to the server specified by the absoluteURI. In order to avoid request loops, a proxy MUST be able to recognize all of its server names, including any aliases, local variations, and the numeric IP address. An example Request-Line would be: GET http://www.w3.org/pub/WWW/TheProject.html HTTP/1.1 To allow for transition to absoluteURIs in all requests in future versions of HTTP, all HTTP/1.1 servers MUST accept the absoluteURI form in requests, even though HTTP/1.1 clients will only generate them in requests to proxies. The absolute URI is defined in RFC 2369, see 3.2.1 in RFC2616: 3.2.1 General Syntax URIs in HTTP can be represented in absolute form or relative to some known base URI [11], depending upon the context of their use. The two forms are differentiated by the fact that absolute URIs always begin with a scheme name followed by a colon. For definitive information on URL syntax and semantics, see "Uniform Resource Identifiers (URI): Generic Syntax and Semantics," RFC 2396 [42] (which replaces RFCs 1738 [4] and RFC 1808 [11]). This specification adopts the definitions of "URI-reference", "absoluteURI", "relativeURI", "port", "host","abs_path", "rel_path", and "authority" from that specification. The HTTP protocol does not place any a priori limit on the length of a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they provide GET-based forms that could generate such URIs. A server SHOULD return 414 (Request-URI Too Long) status if a URI is longer than the server can handle (see section 10.4.15). Note: Servers ought to be cautious about depending on URI lengths above 255 bytes, because some older client or proxy implementations might not properly support these lengths. The absoluteURI is defined in RFC 2396 as follows: 3. URI Syntactic Components The URI syntax is dependent upon the scheme. In general, absolute URI are written as follows: <scheme>:<scheme-specific-part> An absolute URI contains the name of the scheme being used (<scheme>) followed by a colon (":") and then a string (the <scheme-specific- part>) whose interpretation depends on the scheme. The URI syntax does not require that the scheme-specific-part have any general structure or set of semantics which is common among all URI. However, a subset of URI do share a common syntax for representing hierarchical relationships within the namespace. This "generic URI" syntax consists of a sequence of four main components: <scheme>://<authority><path>?<query> each of which, except <scheme>, may be absent from a particular URI. For example, some URI schemes do not allow an <authority> component, and others do not use a <query> component. absoluteURI = scheme ":" ( hier_part | opaque_part ) URI that are hierarchical in nature use the slash "/" character for separating hierarchical components. For some file systems, a "/" character (used to denote the hierarchical structure of a URI) is the delimiter used to construct a file name hierarchy, and thus the URI path will look similar to a file pathname. This does NOT imply that the resource is a file or that the URI maps to an actual filesystem pathname. hier_part = ( net_path | abs_path ) [ "?" query ] net_path = "//" authority [ abs_path ] abs_path = "/" path_segments In section 3.2 of RFC2396 teh athority compnent is specified. It's a bit too long to post now, ut you can find it here: http://rfc.net/rfc2396.html#s3.2. *** However, I do share your opinion that the whole HttpClient 3.0 code is quite old and full of hacks. I hope that this feature will be implemented in future versions using the new API of which you speak.
