NAME

Top

Regexp::Common::URI::http -- Returns a pattern for HTTP URIs.

SYNOPSIS

Top

    use Regexp::Common qw /URI/;

    while (<>) {
        /$RE{URI}{HTTP}/       and  print "Contains an HTTP URI.\n";
    }

DESCRIPTION

Top

$RE{URI}{HTTP}{-scheme}

Provides a regex for an HTTP URI as defined by RFC 2396 (generic syntax) and RFC 2616 (HTTP).

If -scheme => P is specified the pattern P is used as the scheme. By default P is qr/http/. https and https? are reasonable alternatives.

The syntax for an HTTP URI is:

    "http:" "//" host [ ":" port ] [ "/" path [ "?" query ]]

Under {-keep}, the following are returned:

$1

The entire URI.

$2

The scheme.

$3

The host (name or address).

$4

The port (if any).

$5

The absolute path, including the query and leading slash.

$6

The absolute path, including the query, without the leading slash.

$7

The absolute path, without the query or leading slash.

$8

The query, without the question mark.
