?????????????????Version?1.3?（2001-12-13）
--------------------------------------------------------

Introduction:
-------------

This?class?is?a?CAsyncSocket?derived?class.?With?this?class?you
can?connect?through?SOCKS4/5?and?HTTP?1.1?proxies.?This?class?works?
as?semi-transparent?layer?between?you?own?class?and?CAsyncSocket.
This?class?is?used?in?FileZilla?a?powerful?open-source?FTP?client.
It?can?be?found?under?http://sourceforge.net/projects/filezilla
For?more?information?about?SOCKS4/5?goto?

For?more?information?about?HTTP?1.1?goto?http://www.rfc-editor.org
and?search?for?RFC2616

How?to?use?
-----------

You?don‘t?have?to?change?much?in?you?already?existing?code?to?use
CAsyncProxySocket.
To?use?it?you‘ve?to?derive?you?own?class?from?CAsyncProxySocket?and?
you‘ve?to?provide?a?definition?for?OnProxyOperationFailed（int?nOpID）?and?
OnListenFinished（unsigned?long?&retProxyIpint?&retProxyPort）=0;
When?you?create?an?instance?of?your?derived?class?you?should?call
SetProxy.
If?you?overload?the?OnReceive?or?OnConnect?functions?you?have?to?call
CAsyncProxySocket::OnReceive?and?CAsyncProxySocket::OnConnect
as?first?instrucion?in?your?OnReceive?and?OnConnect?functions.
Sample?code:
CMyClass::OnReceive（int?nErrorCode）
{
	CAsyncProxySocket::OnReceive（nErrorCode）;
	//Add?you?own?implementation?below:
	...
}

If?an?operation?fails?OnProxyOperationFailed?is?called.?There
you?can?handle?the?error.?int?nOpID?specifies?the?type?of?the?operation
that?failed:?PROXYOP_CONNECT?when?a?connection?attempt?failed?and
PROXYOP_LISTEN?when?creating?a?listen?socket?failed.

If?you?want?to?use?CAsyncProxySocket?to?create?a?listen?socket?you
have?to?use?this?overloaded?function:
virtual?BOOL?Listen（unsigned?long?serverIp）;
serverIP?is?the?IP?of?the?server?you?are?already?connected?
through?the?SOCKS?proxy.?You?can‘t?use?listen?sockets?over?a
SOCKS?proxy?without?a?primary?connection.?Listen?sockets?are?only?
supported?by?SOCKS?proxies?this?won‘t?work?with?HTTP?proxies.
When?the?listen?socket?is?created?successfully?OnListenFinished?is
called.?The?parameters?unsigned?long?&retProxyIp?and?int?&retProxyPort?
will?tell?you?the?ip?and?the?port?of?the?listen?socket.
After?it?you?have?to?handle?the?OnAccept?message?and?accept?the?
connection.

Description?of?the?new?functions?and?their?parameters:
------------------------------------------------------

void?SetProxy（int?nProxyType）;
void?SetProxy（int?nProxyType?CString?ProxyHost?int?nProxyPort）;
void?SetProxy（int?nProxyType?CString?ProxyHost?int?nProxyPortCString?ProxyUser?CString?ProxyPass）;
	
Call?one?of?this?functions?to?set?the?proxy?type.
Parametes:
-?nProxyType?specifies?the?Proxy?Type.
-?ProxyHost?and?nProxyPort?specify?the?address?of?the?proxy
-?ProxyUser?and?ProxyPass?are?only?available?for?SOCKS5?proxies.

supported?proxy?types:
PROXYTYPE_NOPROXY
PRO
