Question

I just wanted to try out SPDY using the node package “node-spdy”.

My javascript:

EDIT: Now the script includes informations about certificates. I took them from the twitlog test application.

var spdy = require('spdy'),
    fs = require('fs');

var options = {
    key: fs.readFileSync(__dirname + '/keys/spdy-key.pem'),
    cert: fs.readFileSync(__dirname + '/keys/spdy-cert.pem'),
    ca: fs.readFileSync(__dirname + '/keys/spdy-csr.pem')
};

var spdy = require('spdy');

var server = spdy.createServer({}, function(req, res) {
    console.log('Send response...');
    res.writeHead(200, {
        "Content-Type": "text/plain"
    });
    res.write("Hello World!\n");
    res.end();
    console.log('Response has been sended.');
});

server.listen(3000);

My problem: The callback function is never executed, respectively node never logs “Send response…” or “Response has been sended.”. I just get an empty response, but node.js doesn’t throw an exeption:

Fehler 324 (net::ERR_EMPTY_RESPONSE)

My server-side config: I use node.js (version 0.7.6) and node-spdy (commit eafd9c9fdd) under Windows Se7en.

My client-side configuration: I use a chromium build as browser in order to test spdy out. During my tests I don’t use SSL, so I had to change my configuration. That’s what you can find under about:net-internals/#spdy:

==SPDY Status==

SPDY Enabled:               true
Use Alternate Protocol:     false
Force SPDY Always:          true
Force SPDY Over SSL:        false
Next Protocols:

My client-side debug stuff: The chromium debugging service about:net-internals/#tests tells me:

Result  Experiment                      Error                   Time (ms)
FAIL    Fetch http://localhost:3000/
        Don't use any proxy             EMPTY_RESPONSE (-324)   3022

        Fetch http://localhost:3000/
        Use system proxy settings       ?                       ?

EDIT: Since I added certificate infomation, the client-side debugging information changed a bit. Here’s the newest one:

Result  Experiment                      Error                   Time (ms)
FAIL    Fetch https://localhost:3000/
        Don't use any proxy             ABORTED (-3)            9

FAIL    Fetch https://localhost:3000/
        Use system proxy settings       ABORTED (-3)            300489

FAIL    Fetch https://localhost:3000/
        Use Firefox's proxy settings    ABORTED (-3)            4

FAIL    Fetch https://localhost:3000/
        Use system proxy settings       ABORTED (-3)            300438

My server-side debug stuff: That’s what the built-in node debugger tells me when I receive a request:

EDIT: The server-side debug stuff would not change, even if I add certificate information to the scripts.

My question: I just wanna return a simple text message to the client using SPDY. How can I do that using node.js? – If you need some more details, please tell me. Thanks for your answers.

Answer 1

Turn SSL back on. SPDY won’t work without it.
