# Plack::HTTPParser(3pm)

Parse HTTP headers

## NAME

Plack::HTTPParser - Parse HTTP headers

## SYNOPSIS

```
  use Plack::HTTPParser qw(parse_http_request);
  my $ret = parse_http_request($header_str, \%env);
  # see HTTP::Parser::XS docs
```

## DESCRIPTION

Plack::HTTPParser is a wrapper class to dispatch `"parse_http_request"` to Kazuho Oku's XS based HTTP::Parser::XS or pure perl fallback based on David Robins HTTP::Parser.

If you want to force the use of the slower pure perl version even if the fast XS version is available, set the environment variable `"PLACK_HTTP_PARSER_PP"` to 1.
