Description

It appears that gzip headers arent currently supported.

xhr.setRequestHeader("Accept-Encoding","gzip,deflate");

Any chance of adding this? Thx!

    Bump. Would be a nice addition in 1.8

    Folks this feature has been requested for over 6 months now. Gzipping on a slower network is key. Any chance to add this on in 1.8?

    Any news on this is possible?

    Would like to know if this is possible.

    Steps to test: 1. Run the snippet 
       Ti.UI.backgroundColor = '#dddddd';
    
   var url = "https://raw.github.com/appcelerator/Documentation-Examples/master/HTTPClient/data/json.txt";
   var win = Ti.UI.createWindow();
   var table = Ti.UI.createTableView();
   var tableData = [];
   var json, fighters, fighter, i, row, nameLabel, nickLabel;
    
   var xhr = Ti.Network.createHTTPClient({
       onload: function() {
       // Ti.API.debug(this.responseText);
    
       json = JSON.parse(this.responseText);
       for (i = 0; i < json.fighters.length; i++) {
           fighter = json.fighters[i];
           row = Ti.UI.createTableViewRow({
               height:'60dp'
           });
           nameLabel = Ti.UI.createLabel({
               text:fighter.name,
               font:{
                   fontSize:'24dp',
               fontWeight:'bold'
           },
           height:'auto',
           left:'10dp',
           top:'5dp',
           color:'#000',
           touchEnabled:false
           });
           nickLabel = Ti.UI.createLabel({
           text:'"' + fighter.nickname + '"',
           font:{
               fontSize:'16dp'
           },
           height:'auto',
           left:'15dp',
           bottom:'5dp',
           color:'#000',
           touchEnabled:false
           });
    
           row.add(nameLabel);
           row.add(nickLabel);
           tableData.push(row);
           }
    
       table.setData(tableData);
       },
       onerror: function(e) {
       Ti.API.debug("STATUS: " + this.status);
       Ti.API.debug("TEXT:   " + this.responseText);
       Ti.API.debug("ERROR:  " + e.error);
       alert('There was an error retrieving the remote data. Try again.');
       },
       timeout:5000
   });
   
   
   xhr.open("GET", url);
   xhr.setRequestHeader("Accept-Encoding","gzip,deflate"); 
   xhr.send();
    
   win.add(table);
   win.open();
    2. Run the snippet with and without this line and make sure content is identical 
       xhr.setRequestHeader("Accept-Encoding", "gzip,deflate");
    3. Since the json file we're getting info from is very small, you would not see performance difference, which is the main reason for gzipping. Perhaps feed in a bigger json thats 100k-200k large.

    Keep up the good work on this, Hieu - it will be such a valuable addition.

    I have evidence that this is working properly. 1. Upload the following to a public folder in your Dropbox: ~/Library/Applucation\ Support/Titanium/mobilesdk/1.8.0.1/api.jsca Dropbox supports gzip, and api.jsca is a 14mb JSON text file. 2. Drop the below snippet in an app.js and try it out. On my connection, I download the file in about 1.2 seconds. 3. For testing iOS, comment out gzip support in the SDK itself and try again. Also remove the setRequestHeader in your app.js. I averaged 8 seconds per download. We can extrapolate from this that gzip is transmitting a payload 15% the size of the uncompressed version. (Results may vary depending upon the data being transmitted.) 
       var start = new Date().getTime();
   var client = Ti.Network.createHTTPClient({
       onload: function () {
           alert('Request loaded in ' + (new Date().getTime() - start) + 'ms.');
       },
       onerror: function () {
           alert('Failed!');
       }
   });
   client.open('GET', 'http://dl.dropbox.com/u/<;YOUR USER ID>/api.jsca');
   client.setRequestHeader('Accept-Encoding', 'gzip,deflate');
   client.send();

    it would be nice if 'Accept-Encoding: gzip,deflate' is added by default, because this is the behaviour when compiling for iOS
