NAME

       Feersum::Connection - HTTP connection encapsulation

SYNOPSIS

       For a streaming response:

           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

       Encapsulates an HTTP connection to Feersum.  It's roughly analogous to an
       "Apache::Request" or "Apache2::Connection" object, but differs significantly in
       functionality.

       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.
