From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- .../gnu/java/net/protocol/file/Connection.java | 376 ++++++ .../gnu/java/net/protocol/file/Handler.java | 91 ++

+This package contains an HTTP/1.1 client, as described in RFC 2616. +It supports the following features: +

    +
  • Persistent connections
    • +
  • Basic and Digest authentication (RFC 2617)
    • +
  • HTTPS
    • +
  • HTTP proxies
    • +
  • HTTP/1.0 compatibility
    • +
  • Support for WebDAV methods and other HTTP extensions
    • +
  • Automatic decoding of the chunked transfer-coding
    • +
  • Parsing of HTTP date headers
    • +
  • Support for the 100-continue expectation
    • +
+

+ +

+The API is similar to the neon +WebDAV/HTTP library. A logical connection to the server is instantiated, +and multiple requests can be issued for this connection. Each request +has an atomic dispatch method which returns the response. +All I/O, authentication, etc is handled by registering callback objects +with the request prior to dispatch, which are notified during the dispatch +procedure as necessary. Simple byte-array content callbacks are supplied +which can manage any request/response content that fits in available memory. +

+ +

+An URL stream handler is provided, supporting the full HttpURLConnection +specification. +
