=head1 DESCRIPTION |
136
|
|
|
|
|
|
|
|
137
|
|
|
|
|
|
|
This module is plugin for L<IO::Stream> which allow you to route stream |
138
|
|
|
|
|
|
|
through HTTPS (also called CONNECT) proxy. |
139
|
|
|
|
|
|
|
|
140
|
|
|
|
|
|
|
You may use several IO::Stream::Proxy::HTTPS plugins for single IO::Stream |
141
|
|
|
|
|
|
|
object, effectively creating proxy chain (first proxy plugin will define |
142
|
|
|
|
|
|
|
last proxy in a chain). |
143
|
|
|
|
|

=head2 EVENTS |
145
|
|
|
|
|
|
|
|
146
|
|
|
|
|
|
|
When using this plugin event RESOLVED will never be delivered to user because |
147
|
|
|
|
|
|
|
target {host} which user provide to IO::Stream will never be resolved on |
148
|
|
|
|
|
|
|
user side (it will be resolved by HTTPS proxy). |
149
|
|
|
|
|
|
|
|
150
|
|
|
|
|
|
|
Event CONNECTED will be generated after HTTPS proxy successfully connects to |
151
|
|
|
|
|
|
|
target {host} (and not when socket will connect to HTTPS proxy itself). |

171

172

|

You must provide both {host} and {port} to IO::Stream::Proxy::HTTPS->new(). |

175
|
|
|
|
|
|
|
|
176
|
|
|
|
|
|
|
You have provided either {user} or {pass} to IO::Stream::Proxy::HTTPS->new() |
177
|
|
|
|
|
|
|
while you have to provide either both or none of them. |

180
|
|
|
|
|
|
|
|
181
|
|
|
|
|
|
|
You have provided {fh} to IO::Stream->new(), but this is not supported by |
182
|
|
|
|
|
|
|
this plugin. Either don't use this plugin or provide {host}+{port} to |
183
|
|
|
|
|
|
|
IO::Stream->new() instead. |
