一个java写的proxy的例子

2000-11-18    <[e-mail]>

	* transport/dns_lookups.py: changed DNS responses from tuples
	to objects with methods isError, isFound, isRedirect.  This is a
	little cleaner.

2000-11-12    <[e-mail]>

	* proxy4.py: switched to new asyncore from Sam Rushing.
	Updated poll loop to use new meaning of asyncore.socket_map.

2000-05-07    <[e-mail]>

	* transport/http_server.py (ServerConnection): renamed to
	HttpServer, just in case we want other protocols in the future.

	* transport/http_client.py (ClientConnection): renamed to
	HttpClient, just in case we want other protocols in the future.

	* proxy4_base.py: moved Connection into transport/connection.py
	and Listener into transport/Listener.py.

2000-05-04    <[e-mail]>

	* transport/http_server.py (ServerConnection.process): split up
	process into process_<state> for each of the states.  The main
	process function keeps calling a process_<state> function until
	no bytes were processed and the state didn't change.

2000-04-20    <[e-mail]>

	* transport/dns_lookups.py (DnsLookupHostname): started queries on
	multiple nameservers in parallel (staggered)

2000-04-09    <[e-mail]>

	* transport/http_server.py (ServerConnection): added support for
	multiple content/transfer decodings

	* transport/dns_lookups.py (DnsLookupConnection): added support
	for TCP lookups: if the UDP lookups are timing out, try TCP,
	unless previous attempts to use TCP were unsuccessful

2000-04-05    <[e-mail]>

	* proxy4_dns.py: moved to transport/dns_lookups.py
	
	* proxy4_web.py: separated this file into three: transport/
	http_client.py, transport/http_server.py, and
	transport/http_match.py.

2000-03-19    <[e-mail]>

	* proxy4_web.py (ClientServerMatchmaker): persistent connections
	were too complicated to put in the server, so I added a matchmaker
	object whose job it is to find a suitable server and hook it up to
	the client; the matchmaker also limits the number of connections
	per server

2000-03-13    <[e-mail]>

	* proxy4_web.py (ServerConnection): added persistent connections

2000-03-12    <[e-mail]>

	* encoding_chunked.py: added support for the 'chunked'
	Transfer-encoding in HTTP/1.1

	* encoding_gzip.py: added support for the 'gzip' Content-encoding

2000-03-11    <[e-mail]>

	* proxy4_web.py: browser objects and server objects parse headers

2000-03-08    <[e-mail]>

	* proxy4_dns.py (DnsCache): separated pending lookups (`pending'
	field) from the cache (`cache' field) so that we can keep old
	cache values while a new lookup is pending

2000-03-04    <[e-mail]>

	* proxy4_dns.py (DnsExpandHostname): changed DNS lookups to try
	several expansions of names without periods (using search domains
	from /etc/resolv.conf, and also patterns like www.*.com)

2000-03-03    <[e-mail]>

	* proxy4_interp.py: added an Python expression interpreter
	accessible on a separate port; this may be useful for debugging

2000-03-02    <[e-mail]>

	* proxy4_dns.py: moved configuration information to the DnsConfig
	class

	* proxy4_dns.py: changed DNS lookups to try all the DNS servers in
	sequence

2000-02-26    <[e-mail]>

	* proxy4_base.py: added a timer system, where functions can be
	registered to run after some number of seconds

	* proxy4_dns.py: added asynchronous DNS lookups as well as DNS
	lookup sharing (multiple server connections share a single DNS
	lookup, which gets cached)

	* proxy4.py: HTTP proxy based on Sam Rushing's asyncore, with one
	dispatcher per socket connection.
