|
|
973 | |
|
|
974 | Socks proxies are not directly supported by AnyEvent::HTTP. You can |
|
|
975 | compile your perl to support socks, or use an external program such as |
|
|
976 | F<socksify> (dante) or F<tsocks> to make your program use a socks proxy |
|
|
977 | transparently. |
|
|
978 | |
|
|
979 | Alternatively, for AnyEvent::HTTP only, you can use your own |
|
|
980 | C<tcp_connect> function that does the proxy handshake - here is an example |
|
|
981 | that works with socks4a proxies: |
|
|
982 | |

|

998 | on_prepare => sub { $prepare_cb->($_[0]{fh}) }, |
|
|
999 | on_error => sub { $connect_cb->() }, |
|
|
1000 | ; |
|
|
1001 | |
|
|
1002 | $hdl->push_write (pack "CCnNZ*Z*", 4, 1, $port, 1, $socks_user, $host); |

|
|
1019 | possibly after switching off other proxy types: |
