max_message_size and HTTP headers

[GroupCamp]

In P:W:Message the max_message_size is set to 2048 bytes. When one have a large HTTP header sent during the handshake (lets say, a lot of cookies, or cookies with large values, or anything similar), the message is silently rejected, and it is really uneasy to:

• detect something happened
• change the default value

We use P:W via Net::Async::WekSocket::* to manage a WebSocket server, and there is no easy way to carry a different "max_message_size" through the whole system to the P:W:Handshake (despite the fact a large HTTP header is legitimate).

The max_message_size is not even a security : the large message has already been read when the size is tested.

So what do you propose?

AFAIR if you pass max_message_size => undef it will be disabled.

In P:W:Message : $self->{max_message_size} ||= 2048;
In the Net::Async::WebSocket internal, I can change the call to P:W:Handshake::Server to :
my $hs = Protocol::WebSocket::Handshake::Server->new(
req => Protocol::WebSocket::Request->new(max_message_size => 8192)
);
It changes from the default 2048, but 'undef' will not disable the feature...

Maybe having the default value, in an 'our' global in P:W:Message, or in P:W:Handshake::Server (to be used for the Request if provided) would be a good idea : it can be changed globally, with no need to patch Net::Async stuff...
