Lets say I have 2 individually gziped html chunks in memory.
Can I send chunk1+chunk2 to HTTP client? Does any browser supports this?
Or there is no way to do this and I have to gzip the whole stream not individual chunks?
I want to serve to clients for example chunk1+chunk2 and chunk2+chunk1 etc (different order) but I don't want to compress the whole page every time and I dont want to cache the whole page. I want to use precompressed cached chunks and send them.
nodejs code (node v0.10.7):
// creating pre cached data buffers
var zlib = require('zlib');
var chunk1, chunk2;
zlib.gzip(new Buffer('test1'), function(err, data){
chunk1 = data;
});
zlib.gzip(new Buffer('test2'), function(err, data){
chunk2 = data;
});
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain', 'Content-Encoding': 'gzip'});
// writing two pre gziped buffers
res.write(chunk1); // if I send only this one everything is OK
res.write(chunk2); // if I send two chunks Chrome trying to download file
res.end();
}).listen(8080);
When my example server returns this kind of response Chrome browser display download window (it doesnt understand it :/
