NAME

SYNOPSIS

    Feersum->endjinn->request_handler(sub {
        my $req = shift; # this is a Feersum::Connection object
        my $env = $req->env();
        my $w = $req->start_streaming(200, ['Content-Type' => 'text/plain']);
        # then immediately or after some time:
        $w->write("Ergrates ");
        $w->write(\"FTW.");
        $w->close();
    });

For a response with a Content-Length header:

    Feersum->endjinn->request_handler(sub {
        my $req = shift; # this is a Feersum::Connection object
        my $env = $req->env();
        $req->start_whole_response(200, ['Content-Type' => 'text/plain']);
        $req->write_whole_body(\"Ergrates FTW.");
    });

DESCRIPTION

Until Keep-Alive functionality is supported (if ever) this means that a connection is also a request.

See Feersum for more examples on usage.

METHODS

"my $env = $req->env()"

Obtain an environment hash. This hash contains the same entries as for a PSGI handler environment hash. See Feersum for details on the contents.

This is a method instead of a parameter so that future versions of Feersum can request a slice of the hash for speed.

"my $w = $req->start_streaming($code, \@headers)"

A full HTTP header section is sent with "Transfer-Encoding: chunked" (or "Connection: close" for HTTP/1.0 clients).

Returns a "Feersum::Connection::Writer" handle which should be used to complete the response. See Feersum::Connection::Handle for methods.

"$req->send_response($code, \@headers, $body)"

"$req->send_response($code, \@headers, \@body)"

Respond with a full HTTP header (including "Content-Length") and body.

Returns the number of bytes calculated for the body.

"$req->force_http10"

"$req->force_http11"

Force the response to use HTTP/1.0 or HTTP/1.1, respectively.

Normally, if the request was made with 1.1 then Feersum uses HTTP/1.1 for the response, otherwise HTTP/1.0 is used (this includes requests made with the HTTP "0.9" non-declaration).

For streaming under HTTP/1.1 "Transfer-Encoding: chunked" is used, otherwise a "Connection: close" stream-style is used (with the usual non-guarantees about delivery). You may know about certain user-agents that support/don't-support T-E:chunked, so this is how you can override that.

Supposedly clients and a lot of proxies support the "Connection: close" stream-style, see support in Varnish at http://www.varnish-cache.org/trac/ticket/400

"$req->fileno"

The socket file-descriptor number for this connection.

"$req->response_guard($guard)"

Register a guard to be triggered when the response is completely sent and the socket is closed. A "guard" in this context is some object that will do something interesting in its DESTROY/DEMOLISH method. For example, Guard.
