7       information

SYNOPSIS

10         use HTTP::ProxyAutoConfig;
11
12         my $pac = HTTP::ProxyAutoConfig->new("http://foo.bar/auto-proxy.pac");
13         my $pac = new HTTP::ProxyAutoConfig('/Documents and Settings/me/proxy.pac');
14         my $pac = HTTP::ProxyAutoConfig->new();
15
16         my $proxy = $pac->FindProxy('http://www.yahoo.com');

DESCRIPTION

19       HTTP::ProxyAutoConfig allows perl scripts that need to access the
20       Internet to determine whether to do so via a proxy server.  To do this,
21       it uses proxy settings provided by an IT department, either on the Web
22       or in a browser's .pac file on disk.
23
24       It provides means to find the proxy server (or lack of one) for a given
25       URL.  If your application has located either a wpad.dat file or a .pac
26       file, HTTP::ProxyAutoConfig processes it to determine how to handle a
27       particular destination URL.  If it's not given a wpad.dat or .pac file,
28       HTTP::ProxyAutoConfig tests environment variables to determine whether
29       there's a proxy server.
30
31       A wpad.dat or .pac file contains a JavaScript function called
32       FindProxyForURL.  This module allows you to call the function to learn
33       how to access various URLs.
34
35       Mapping from a URL to the proxy information is provided by a
36       FindProxyForURL(url, host) or FindProxy(url) function call.  Both
37       functions return a string that tells your application what to do,
38       namely a direct connection to the Internet or a connection via a proxy
39       server.
40
41       The Proxy Auto Config format and rules were originally developed at
42       Netscape.  The Netscape documentation is archived at
43       <http://linuxmafia.com/faq/Web/autoproxy.html>

METHODS

53   new( url_or_file )
54       This call creates the FindProxyForURL function and the object through
55       which it can be called. The url_or_file argument is optional, and
56       points to the auto-proxy file provided on your network or a file used
57       by your browser.  If there is no argument, HTTP::ProxyAutoConfig will
58       check the http_auto_proxy environment variable, followed by the
59       http_proxy, https_proxy, and ftp_proxy variables.
60
61       As shown above, you can use either the HTTP::ProxyAutoConfig->new() or
62       the new HTTP::ProxyAutoConfig() form, but don't use the
63       HTTP::ProxyAutoConfig::new() form.
64
65   FindProxyForURL( url, host )
66       This takes the url, and the host (minus port) from the URL, and
67       determines the action you should take to contact that host.  It returns
68       one of three strings:
69
70         DIRECT           - connect directly
71         PROXY host:port  - connect via the proxy
72         SOCKS host:port  - connect via SOCKS
73
74       This result can be used to configure a net-access module like LWP.
75
76   FindProxy( url )
77       Same as the previous call, except you don't have to extract the host
78       from the URL.
