thanks for looking & solving. Yes I see now the recv loop should read a stream and work out when to stop pulling more bytes from recv(), In my full code I extract the chucked hex later for decompressing gzip, I'll have to read the header & chunk in the while(recv loop.

When i read about keep-alive I believe the Apache server is meant to wait for timout of at least 5 seconds (after handling a request), but my recv loop finishes pretty instantly after recieving 3-4 HTTP packets for the entire gzip webpage (in my full code).

I'm guessing somehow the server sees a request for more information and Apache has code to detect clients with while(recv() != 0).

NAME
HTTP::Daemon::SSL - a simple http server class with SSL support SYNOPSIS
use HTTP::Daemon::SSL; use HTTP::Status; # Make sure you have a certs/ directory with "server-cert.pem" # and "server-key.pem" in it before running this! my $d = HTTP::Daemon::SSL->new || die; print "Please contact me at: <URL:", $d->url, "> "; while (my $c = $d->accept) { while (my $r = $c->get_request) { if ($r->method eq 'GET' and $r->url->path eq "/xyzzy") { # remember, this is *not* recommened practice :-) $c->send_file_response("/etc/passwd"); } else { $c->send_error(RC_FORBIDDEN) } } $c->close; undef($c); } DESCRIPTION
Instances of the HTTP::Daemon::SSL class are HTTP/1.1 servers that listen on a socket for incoming requests. The HTTP::Daemon::SSL is a sub-class of IO::Socket::SSL, so you can perform socket operations directly on it too. The accept() method will return when a connection from a client is available. In a scalar context the returned value will be a reference to a object of the HTTP::Daemon::ClientConn::SSL class which is another IO::Socket::SSL subclass. In a list context a two-element array is returned containing the new HTTP::Daemon::ClientConn::SSL reference and the peer address; the list will be empty upon failure. (Note that version 1.02 erroneously did not honour list context). Calling the get_request() method on the HTTP::Daemon::ClientConn::SSL object will read data from the client and return an HTTP::Request object reference. This HTTPS daemon does not fork(2) for you. Your application, i.e. the user of the HTTP::Daemon::SSL is reponsible for forking if that is desirable. Also note that the user is responsible for generating responses that conform to the HTTP/1.1 protocol. The HTTP::Daemon::ClientConn class provides some methods that make this easier. METHODS
The following methods are the only differences from the HTTP::Daemon base class: $d = new HTTP::Daemon::SSL The constructor takes the same parameters as the IO::Socket::SSL constructor. It can also be called without specifying any parameters, but you will have to make sure that you have an SSL certificate and key for the server in certs/server-cert.pem and certs/server-key.pem. See the IO::Socket::SSL documentation for how to change these default locations and specify many other aspects of SSL behavior. The daemon will then set up a listen queue of 5 connections and allocate some random port number. A server that wants to bind to some specific address on the standard HTTPS port will be constructed like this: $d = new HTTP::Daemon::SSL LocalAddr => 'www.someplace.com', LocalPort => 443; SEE ALSO
